Two handy knitted increases, one slanting right, one slanting left

These increases are nearly identical, but the right leaning increase is a forwards loop while the left-slanting increase is a backwards loop. (These increases are really just subsets of the forward and backward looping-on casting-on described in a previous post. However, instead of casting-on an entire row of foundation stitches, only one stitch at a time is being cast on, to serve as an increase.)  These kinds of loop increases are often called an m1 (make-1) although, in truth, there are LOTS of different increases called an m1.

(Above) The fabric in this picture is growing to the right because the increases are being made very near the fabric's right edge (one stitch in from the edge, actually). The increases are right-slanting ones, which means that they lay smoothly and do not leave a bump on the fabric surface when used to make an increase by the right edge of a knitted fabric. This right-leaning looped increase is made by twisting the standing yarn UNDER the tail yarn (in this illustration, the tail yarn=yarn coming out of the immediately preceding stitch).

The loop which results from twisting the standing yarn under the tail yarn is called a "forwards" loop because the loop lays on the right needle right arm forward, just like a regular untwisted stitch does. In other words, if you compare the right-leaning increase to the ordinary stitch sitting beside it you will see that both lay right arms forward.

(Above) The fabric in this picture is growing to the left because the increases are being made very near the fabric's left edge (one stitch in from the edge). The increases are left-leaning ones, which means that they lay smoothly and do not leave a bump on the fabric surface when used to make an increase by the left edge of a knitted fabric. This left leaning looped increase is made by twisting the standing yarn OVER the tail yarn (in this illustration, the tail yarn=yarn coming out of the immediately preceding stitch).

The loop which results from twisting the standing yarn over the tail yarn is called a "backwards" loop because the loop lays on the left needle "backwards," like a twisted stitch would. Compare the left-leaning increase to the regular stitch sitting beside it--the regular stitch is right arm forward, but the increase loop is left arm forward.

* * *

The easiest way to make both of these increases is to pinch the standing yarn between your left thumb and forefinger, twist it into the kind of loop you want (per illustrations above) and then place it onto the right needle.

* * *

Initially, you may find knitting (or purling) into looped increases awkward. Like all looped-on stitches, looped increases--whether left- or right-leaning--want to shrink and stretch and share yarn with the surrounding stitches. If you're really having a hard time skewering those loops with your right needle when you come to them in the next row, cheat a little, and knit (or in flat knitting, purl) into the back loop instead. I made two long samples--one flat knit and one circular knit, and could see only the most subtle difference between working into the front loops or working into the back loops, so do whatever you'd find easiest. With practice, knitting into these awkward little thingies will become one more of your "mad knitting skillz" (as the 8th graders like to say).

Knitting seamless tubes & circles-part 2: the theory

The first post of this series tried to convince you of the wisdom of learning to make seamless tubes and circles. Today's post examines the theory What is the theory behind the voodoo of double pointed needles, as well as magic loop.

Future posts will get down to the actual (k)nitty-gritty--how to hold 4 (5?) needles with two hands, how to cast on, all that good stuff. But for today, we're not going to worry about how the stitches are cast on, or how they find their way from one needle to the next, or ladders, or any of that stuff. Today, we're just going to look at some stitches ALREADY ON the needles. Today, we're dealing with--

The THEORY of seamless tubes and circles 101

The traditional way of knitting small tubes or circles is with 4 or 5 double pointed needles (dpn's). But nobody has that many hands, and the thing looks horribly complicated. The alternate non-traditional method--using one very long circular needle--a method called "Magic loop"-- also looks complex.

Given how un-intuitive these methods seem, there must be a pretty good reason why they're so popular. So what is that reason? What's with all those needles, all those darn loops?

The WHY of DOUBLE POINTED NEEDLES

The deal is this: double pointed needles (dpn's) allow your knitting to choose its own natural diameter. This is true whether you are knitting a pass-through tube (sleeve) or a dead-end tube (hat, sock, mitten)--or any flat circle (lace shawl, hat top)--on dpn's these items all get to find their natural diameter without any stretching.

An example: per the illustration below, if you have a tube of 44 stitches, and you put that on four dpn's, you'll have 11 stitches on each of the four needles, right? Each SET of 11 stitches can just sit in the middle of its own personal needle, taking up exactly 11 stitches worth of needle-room. The stitches in each set never need to stretch their way down the length of the needle. Any unused lengths of needle just turn into naked needle ends sticking out PAST either end of the set. As a result, the tube gets to hang down from the needles in its natural shape--at its natural diameter.

Now, the thing is, the naked needle ends on the dpn's are free to overlap one another as much or as little as necessary. That's what makes the dpn system so very flexible. On the illustration below, if you were to increase one stitch per set--so you had 12 stitches on each of 4 needles, each needle would have less naked needle-end, and more of each needle would be taken up with stitches. In this way the tube would remain free to find its own diameter.

So it all boils down to this: stitches on dpn's don't have to stretch ALONG the needle--the excess needle just sticks out. That means there's no gap between the stitches of one set. But, how about the gap BETWEEN sets?
click picture
44 sts on dpn'sLet's look at the gap between stitch 11 and stitch 12 in the above illustration. It is true that two needle ends are sticking out of this gap. However, although there is a right angle bend between them, stitch 11 (the LAST stitch of one set) and stitch 12 (the FIRST stitch of the next set) aren't really any further apart from one another than if they were two stitches in the SAME set. In other words, they're just as close to one another as they would be if they were on the same needle. See: the knitted fabric is flexible, bends readily and easily accomodates the right turn between each set of 11 stitches, while the naked needle ends overlap as much (or little) as they need to, to keep adjoining stitches from different sets right next to each other.

Bottom line: with dpn's, there is no stretching between stitches in the same set, nor between stitches in adjoining sets. The dpn's let the tube you're knitting find its own diameter, and any excess length of needle just sticks out PAST the stitches.

Of course, the whole thing looks like a porcupine, with all those naked needle ends sticking out. And that is especially so when you're just starting a center-start garment with a very few stitches. However, within that ferocious-looking nest of needle ends, the tube or circle lays very nice and tidy and most of all it lays peacefully UNSTRETCHED.

The WHY of a too-long circular needle (called "Magic Loop")

We now pass on to the trick of knitting with a too-long circular needle. This trick was popularized in a booklet which named the technique "Magic loop" knitting. The booklet, available on the web, and probably at your LYS, came out around the same time as modern circular needles which feature a well-attached and flexible cable.  This technique is a needle-ruiner for the older type needles with stiff nylon cables, which will kink or break at the cable-needle joint.

Oh wait--one more thing before we jump in. I expect you are wondering why this trick even developed--after all, it seems sort of odd to create a small seamless tube with a too-long needle. Why not just use an itty-bitty teeny circular needle in the first place? Actually, there ARE tiny needles touted for making little tubes--needles 8 inches long and 12 inches long. However, for many knitters, a needle that short is hard to manipulate. The needle tips have to be very short or the cable wouldn't be long enough to wrap around the back, so you have to hold the needle tips with your finger tips.

OK, now we come to the theory of the technique.

The deal with a too-long circular needle is this: by popping two loops of cable out between two sets of adjacent stitches, the stitches separate into two sets in a flattened sort of tube. As with dpn's, disassociating the length of the needle from the amount of room each set of stitches takes up, allows the stitches in each set to sit unstretched, taking up exactly as much needle-room as they need.

In other words, in the same way that the naked needle-ends protrude past the ends of the stitch sets in dpn's, so unused part of the cable needle protrudes in loops past the ends of the stitch sets in this technique. Because the cable loops are free to stick out of the fabric as far or as little as necessary, this allows the tube you are knitting to find its natural diameter without stretching around the circumference of the circular needle.
click picture
Between stitches 22 and 23, in the illustration above, the first loop of excess cable has been popped loose of the fabric, and between stitches 44 and 1, the second loop of excess cable has been popped loose. (Notice that the front set of stitches lies on the left needle tip, but the back set of stitches isn't actually on the right needle tip--it is on the cable. The right needle has been drawn all the way around, and is positioned ready to knit the waiting stitches off the left needle.)

The cable loop which pokes out between sets is theoretically flexible enough so that stitches in adjoining sets are no further apart than stitches along the same needle in the same set, and the knitted fabric is theoretically flexible enough to take the 180 degree bend between the front and back set of stitches without distortion. In actual practice, you may find that there is distortion along the line between the front and the back sets of stitches.

WHICH METHOD WHEN?

Like every other aspect of knitting, personal preference trumps all.  For me, magic loop, with its flattened, doubled fabric, is a perfect match for creating objects which are used flat and doubled--classic ski hats, diamond-shaped potholders, christmas stockings. This is partly because magic loop tends to distort the fabric slightly along the fold line making it a good match for objects which will stay folded, and partly because with magic loop, it is so easy to visualize what the finished project will look like since you knit it in the same shape as it will be used.

Other than for folded, doubled objects, I don't use magic loop much because I find it slow to have to stop and re-arrange the needles twice on every round--that'd be every 30 or 40 stitches on a sock, for example. In my hands, double pointed needles are much faster.

However, as is evident in the comments, this is utterly a question of preference.  Some knitters find that magic loop is quite a bit faster than dpn's, and more convenient, too: easier for travel, less likely to lose needles, no need to own multiple sets of needles.

It's knitter's choice, and after a few iterations, you'll know which trick works better for you.

Knitting seamless tubes & circles-part 1: why to learn double pointed needle & magic-loop

too many needlesThere are two kinds of tubes in knitting: pass-through tubes (like sleeves) and dead-end tubes, like socks, mittens and hats. Often, patterns call for making these seamlessly using a special skill --using double pointed needles (dpn's) or by using an alternate method, such as using a too-long circular needle called "magic loop" (after a pioneering book--well worth owning!!--of this same name).

This special skill may be used for the whole garment (knitting a sweater in the round) or for part of a garment (the sleeves on double pointed needles). It may be modified into flat or flat-ish circle knitting for the dead-end part of a hat, sock, thumb; or for the center start--or end--of a hat, or flat shawl or blanket.

Now, the thing is, many knitters dread dpn's or magic loop to the point of avoiding them. Worse yet, some knitters avoid even thinking about learning how--it looks too complicated, too fussy, too much like something for an octopus with 8 hands, rather than a knitter with only 2.

This is the first in a series of posts--eventually this series is going to lead into 1) a how-to on operating dpn's, and 2) a how-to about knitting tubes and circles with magic-loop on one too-long circular needle. But there's no sense starting with the "how to" if you don't think the effort is worth it in the first place.

In the hopes of persuading the dpn-o-phobic, the seamless-tube-o-phobic, the "center-start"-o-phobic, the "magic-loop"-o-phobic to change their ways, here's a piece on why you might bother to learn in the first place.

WHY BOTHER LEARNING TO KNIT SEAMLESS TUBES AND CIRCLES?

You could make a tube by creating a piece of flat cloth, and then sewing it up. That's actually how most clothing IS made--the fine art of dressmaking involves taking flat cloth and forming it into tubes that (like Swift's fleas, ) have littler tubes upon 'em--a big pass-through tube for the body, smaller attached sleevish pass-through ones for the arms and legs, little dead-end tubes for the hands and feet , sometimes with littler dead-end tubes yet upon those--the fingers in gloves, the thumbs in mittens.

Folding flat rectangles into tubes isn't restricted to woven cloth--knitting can be done this way too--that's what all the recipes for sweaters in 5 pieces are about, and "two needle" mittens and hats--knitting a flat piece or panel of cloth to be sewn up along various specified edges into the tube of choice.

In dressmaking (as the sewers among you know) there are limitations to tube-creation. First and most obviously, people stretch, but woven cloth doesn't--or doesn't very well except along the bias, and even that is very limited. So in order to create wearable tubes, there are two possible approaches. First, the tubes can be made roomy enough to move around inside of (they have to have sufficient "ease"). An alternative approach is to create tubes fitted to the body (by gores, panels, sleeve caps or darts) so the excess cloth necessary for ease does not bind. These fitted garments have to be provided with openings to let the wearer climb inside them (plackets) and also be provided with a method for closing these openings (zippers, buttons).

Using stretchy fabric, like knitting, makes a lot of these problems go away. Because the knitted fabric IS so stretchy, less ease, less shaping and fewer openings have to be provided. And this is especially true for pass-through tubes. If your hand can pass through the sleeve and pop through the cuff, but the cuff stays small enough to snug around your wrist, you don't have to sew (and face) a slit cuff with a placket, button band and buttons. Less work all around, and more comfortable, too.

So, if you are knitting flat fabric and sewing it together into tubes, you're already got woven cloth garments beat all hollow for stretchy comfort. And perhaps, that is where you are inclined to stay--with seamed two-needle, pass-through-tube-garments, knitted flat. But, although seamed knitting is far superior in stretch and comfort to seamed woven fabric, there are problems with seaming even knitted fabric.

A seam of a sewn tube stops the stretchy knit fabric from stretching. Stopping stretchy-ness isn't much of a problem on a big pass-through tube, like a sweater body--it might even be a sag-stopping advantage. But on a small tube, like a sleeve, the situation is dicier.

When we turn to dead-end tubes, the problem only gets worse. On a tiny tube like a mitten thumb or glove finger, or even on a sock, lack of stretchy-ness IS a problem. When knitted socks and stockings were first invented, their stretchy properties were so astoundingly comfortable compared to the non-stretchy footwear they replaced, that they were considered precious objects--worth breaking and entering for, and listed in the inventories of rich folks' estates. Knitted stockings were presents considered fit for royalty.

And lack of stretchy-ness isn't the only problem raised by seaming knitted fabric. You see, the smaller the tube, the greater the proportion of the tube which is taken over by the (possibly unsightly, possibly bulky, possibly uncomfortable) seam. Trying to cram your actual finger AND a seam into a glove finger of proportionate size might be a trick. The seam in a sock could be painful to tread upon. Heads are harder than fingers and toes, but it still might be annoying to have the knot of a hat seam on your forehead, ear or the back of your neck.

OK, so in the best of all possible worlds, we'd all knit seamless tubes, right? Make ourselves a pair of socks fit for the queen of England? And maybe you'd be willing to read more about the idea behind all those double pointed needles? Or how it works to make a little tube with a big long circular needle twisted into a "magic loop?" Stay tuned until the next post--part 2 of knitting seamless tubes & circles.

Felted mittens with non-felted cuffs

My LYS had a book about felting on display. The book had a section on children's mittens. It recommended casting on in cotton, knitting a few rounds, switching to wool, making the mittens, felting the mittens, removing the waste cotton and then knitting the cuff into the holes where the cotton had been.

Hmmm. Well...it would work, yes. You COULD do it that way. But...why? What a lot of work.

Try this instead:

Here are the same mittens after two Wisconsin winters' worth of wear by a boy, now in second grade, who wears these mittens (and no others) through every snowball fight and sledding adventure, every day at recess, after school and every other time he goes outside--and here, we've still got a foot on the ground (although thankfully, it is melting fast). These mittens are getting too small for him now, the bright colors have yellowed and faded, but he's still wearing them.

Where the ribbing ends: improving the transition zone

click picture
ribbing transition zonesincludes a how-to
The transition zone where the ribbing meets the sweater (hat, mitten) is the subject of today's post.
* * *
Where the ribbing meets the sweater is often a weak spot in knitting. Along with the change of stitch pattern comes a distortion in the column of knit stitches, especially when switching from ribbing to stockinette fabric. Although this is no earth-shattering condition, it's so easy to improve that you might as well--for the cumulative effect of little improvements is greater than you might believe.

For various arcane reasons, the transition zone between ribbing and the body of the garment is actually more of a problem for top-down ribbing. Therefore, as the second photo below demonstrates, the improvement is correspondingly more dramatic for top-down knitting. However, the first photo shows that bottom-up ribbing also benefits from an improved transition zone.

Here is the how-to:

FOR RIBBING STARTED FROM THE BOTTOM UP

For the purposes of this discussion, I assume you are at the point where you are going to switch FROM ribbing TO stockinette or a patterned fabric.
  • On the LAST ribbing row, SLIP every knit stitch (slip them "open," also called purlwise"). Purl every purl stitch.
  • After this last row or round of ribbing, switch to the larger needle you'll use for the body size, and begin the body of the garment.
click picturetop down 1x1 ribbing
(Photo above) In bottom-up ribbing, the improvement is subtle, but still visible. The corrected knit columns bridge more directly from the ribbing to the body of the fabric (right arrow). Although it's hard to tell from this photo, the uncorrected transition zone (left arrow) features a bulkier transition from ribbing to the smoother stockinette fabric of the garment body.

FOR RIBBING STARTED FROM THE TOP DOWN
For the purposes of this discussion, I assume you have worked your garment down to the point where you want your ribbing to start.
  • Using the needle size for the ribbing (usually a needle 2-3 sizes smaller than that with which you worked the body of the garment) work one last row or round in the body pattern (i.e.: the last row of stockinette, or whatever you were working).
  • On the next row or round (the first row of ribbing) SLIP every knit stitch (slip them "open," also called purlwise.") Purl every purl stitch.
  • After this first row or round, work the ribbing in the usual way to the desired length.
click picture
top down 2x2 ribbing(Photo above) The corrected knit columns bridge more directly from the body of the fabric to the ribbing (right arrow). The unimproved transition zone (left arrow) features wandering, zig-zagging knit columns.
* * *

ribbing w/increasesMarjorie, a reader of this blog, asks the excellent question of how to reconcile the technique set forth in the post--slipping the knit stitches--with the advice often given in patterns to start bottom-up ribbing on fewer stitches, and then increase to the larger body number of sitches "evenly in the last row." Per the photo (left) if the fabric above the ribbing is to be stockinette, or a near-stockinette fabric, it would be my advice to do all increases on a purl using an increase, such as backwards loop, which leaves a "bump." This "bump" will blend into the purls. By not making increases on the knit columns you will have preserved the attractive transition where the knit columns of the ribbing segue into the knit columns of the stockinette fabric above it.


* * *
A final note: although 1X1 ribbing is demonstrated in bottom-up knitting, and 2X2 ribbing is demonstrated in top-down knitting, the directions given for bottom-up ribbing work for both 1X1 AND 2X2 ribbing worked from the bottom up.

Similarly, the directions given for top-down ribbing work for both 1X1 AND 2X2 ribbing worked from the top down.

If you want to work a 3X3 or larger, do a swatch to decide for yourself whether the slip-the-knit-stitches technique creates a noticible improvement over so wide a rib.

The TKIO--a cute way to start hats

includes a how-to
Following the idea that it is the little details which make the difference between "home made" and "handmade," here is a little "unvention:"* the TKIO, pronounced "Tik-ee-o." It's the TechKnitting way of making a little I-cord "O," a cute loop to begin a center-start hat, or a knitted ornament, or an egg cozy, or a potholder, or any other object made in the round. (Click pictures for close-ups.)

Really, you can make this little dingus any way you want to: at its heart, it is nothing but a short length of I-cord, with live stitches at both ends, doubled over and the stitches distributed onto double pointed needles (dpn's). If you already have a favorite method for getting live stitches on both ends of something, just skip to the photos in steps 5 and 6 below to get the idea, and then do it your way.

The rest of this post is about how I cast on TKIOs. If you're still with me, here's the--

HOW-TO
Step 1
click picture
step 1 TKIO(Above) Cast four stitches on a double pointed needle by the backwards loop method. DOUBLE TWIST the first stitch (the double twist holds it on better for what follows).

Step 2
click picture
step 2 TKIO(Above) Slide the 4 stitches to the right tip of the CO needle, and bring the standing yarn behind the work. Insert a second needle into the space between the first 2 backwards loops and draw up a loop of the standing yarn (standing yarn=yarn coming from the ball). In other words, reach through the space between the first and second backwards loops, draw up a loop of standing yarn, and keep it on the second needle.

Step 3
click picture
step 3 TKIO(Above) Repeat this loop-drawing up manuever between the 2nd and 3rd CO stitch, and again between the 3rd and 4th CO stitch. You will have 7 stitches on two needles--4 on the top needle, 3 on the bottom needle. Push the first stitch cast on--the double twisted one--off the right tip of the top needle. Now you will have 6 stitches--3 on top, 3 on the bottom.

Step 4
click picture
step 4 TKIO(Above) Knit a short length of I-cord on the TOP set of stitches, as illustrated, leaving the lower stitches ON THE LOWER NEEDLE.(TIP: If your lower 3 stitches seem to be very loose --AS ILLUSTRATED IN PICTURE 5-- catch the tail end together with the standing yarn and knit them together for the first stitch of the I-cord. On the next row of the I-cord, don't be confused that there are 4 stitches on your needle--remember to knit these two overlapped stiches as if they were one. Snug up the tail end and the bottom three stitches will stay tight.)

Step 5
click picture
(Left) The short I-cord on the needles. (See notes to step 4 regarding the loose stitches on the bottom needle.)

Step 6
click picture
step 6 TKIO(Right) When the I-cord is as long as you want it, push the three top stitches to the left tip of the top needle. Hold the right tip of the bottom needle to the left of the 3 stitches on the top needle and join by knitting 2 of the bottom stitches off onto a third needle. The result: the TKIO's six stitches (3 from the I-cord top, and the 3 from the lower needle) will be distributed in pairs onto 3 double pointed needles (dpn's) ready to knit further in any center-started pattern which needs a cute little hanging loop. (Tip: when joining, keep the "inside in." I-cord has a beautiful side--the front--and a less-beautiful side--the back, which often features the ladder-ish gap which formed between stitches 3 and 1. Hide this gap on the inside of the loop when you double it over.)

ADDENDUM October 2009: I went and knitted with a bunch of knitters in Utrecht, Holland, and they call these little loops "Teletubbies!!"

--TECHknitter
*As Marie Antoinette's hatmaker said: "Nothing is new but that which has been forgotten." In that spirit, I am confident that the TKIO exists somewhere else with a different name, and that I have not "invented" it. However, I never saw another and so (to use Elizabeth Zimmerman's famous phrase) have "unvented" it.

Mysteries of knitting part 1 - A tale of heads and arms, or: "why does stockinette curl but ribbing doesn't?"

Do you wonder why stockinette fabric curls and ribbing doesn't (and garter doesn't, and seed stitch doesn't)? Does it puzzle you why stockinette sometimes curls from side-to-side, and sometimes from end-to-end? Does it confuse you that garter stitch and reverse stockinette look so alike? Is it mysterious to you that "nothing but knit" makes stockinette if worked in the round, but makes garter stitch if worked flat?

These questions may seem random and unrelated, but they're not--the same explanation answers all.

If you're still interested, stick tight. It's a long post and there are going to be a few concepts juggled in the air, all at the same time. But, if you're willing to plow through three little experiments and a couple of explanations, let's go...

click picture
naming the stitch
Naming the stitch
Knitting, as you know, consists of loops drawn through other loops. Now, a loop is a fluid little creature. It's hard to say where one loop begins and the next one ends (which is one reason that knitting is so nice and stretchy). But once we pin this down, once we name the parts, knitting gets a lot less mysterious.

I'm going to arbitrarily name some parts of a knitted stitch: I'm going to say that it has *a head* and *two arms.* In some writing about knitting, the arms are called "legs". (A knitted loop also has a tail, but that is for a different post. We are mostly ignoring the tail for right now.)


First little experiment
Aligning heads and arms

Cast on 10 stitches any way you like, and make a tiny bit of stockinette: a knit row, a purl row, another knit row and another purl row. Knit three more stitches on your next knit row (no magic here--those three stitches are just to get you away from the distractions of the edge) and, here we go ...

When we "knit," we draw the new loop through the old so as to HIDE THE HEAD and EXPOSE THE ARMS of the old stitch. In more technical terms, we are aligning all the heads on the back face of the fabric, and all the arms on the front face of the fabric.

Do it. Knit one stitch. Peer over the edge of your needle--see how you're popping the head of the old stitch to the BACK of the fabric? Look again at the side on which you are working--see how you're lining up the little arms in V's on the FRONT of the fabric? See how ALL the heads with their nubby little bumpy heads are lined up on the BACK of the fabric? See how ALL the arms with their pretty little V's are lined up on the FRONT of the fabric? See how I can't get off the SHIFT key? That's because all these things are IMPORTANT, people!

The result: Due to the way the knit stitch aligns the head and arms, stockinette fabric features all the arms on the "front" of the fabric, where they lay nice and smooth, while all the bumpy heads were popped to the back, where they lie mostly hidden on the other side of the fabric.
click picture
stockinette fabricNow knit to the end of your row, watching the head-popping, arm-aligning miracle of each knit stitch and ... get ready to purl. Oooh. The excitement!

Purl three stitches (again, just to get away from the edge) and now watch what happens as you purl the fourth stitch. When we "purl," we do the exact opposite of knitting. This time we draw the new loop through so as to HIDE THE ARMS and EXPOSE THE HEAD of the old stitch. In more technical terms: just like with the knit stitch, we are again aligning all the heads on the one face of the fabric, and all the arms on the other face of the fabric. However, purl pops the head TOWARDS you, while knit pops it AWAY from you. Because you've turned the fabric around between your knit row and your purl row, purling the head TOWARDS you on the fabric back and knitting it AWAY from you on the fabric front creates that alignment I've been yammering about.

The result: All the heads are on the "front" of this reverse stockinette fabric, where they lay nice and nubbly, while all the smooth arms lie hidden on the back of the fabric.

reverse stockinette fabric
Second little experiment
Why stockinette sometimes curls side-to-side,
and sometimes curls top-to-bottom

Purl to the end of the row, and let's look at the front of that little swatch one more time together.

click picturelong skinny curl
See all the little V's of the arms on the front of the fabric? Those little V's, being 2 pieces of vertical yarn laying side-by-side, are WIDER than the head, which is only 1 little piece of horizontal yarn. (OK, there's also the tail which we are ignoring for right now-but that's horizontal too.) In addition, all those vertically aligned arms laying side by side are jostling for position--they're pushing on each other side-to-side, repelling one another like incompatible magnets. The result is a fabric which is actually WIDER on the front than the back!

Because the front is wider, stockinette curls from side to side with the knit face out. And this is also why you can't block the curl out of a stockinette scarf --the curl is built right into the structure of the fabric.

But wait a minute--the little scrap on your needles--yes, it is curling from side to side a little bit, but what it's really doing is trying to curl top-to-bottom into a horizontal tube--what's with that?

Well, part of the answer is that your needle is pinning the fabric, stopping it from expressing its side-to-side roll. But the real truth is even stranger.

You see, just as stockinette fabric is wider on the front than the back, it is LONGER on the back than the front. The heads (and tails!) draw a great deal of horizontally aligned yarn onto the back, so there's more horizontal yarn on the back than the front. All those horizontal heads are jostling for space back there--they are pushing each other away, repelling one another, making the fabric curl over end-to-end (top-to-bottom).

reverse stockinette knitted short and wideIf this is still confusing, here's one more run at it: If you put all the arms on ONE side of the fabric, then all the heads (and tails!) on the OTHER side, you get something surreal--something out of one of those melty Dali paintings--a fabric that's actually WIDER on the front than the back, and LONGER on the back than the front. In a long skinny piece of stockinette (a scarf) the side-to-side curl of the wider front fabric will predominate, in a short wide piece of stockinette (your 6 row swatch, a cast-off edge at a neckline or hat brim) the top-to-bottom curl of the longer back fabric will predominate.

Third little experiment
Why stockinette curls and ribbing doesn't
(and garter doesn't, and seed stitch doesn't)


So--now that we've been splashing around in the concepts of head alignment and arm alignment, we're finally ready to answer the question about why stockinette curls, and ribbing doesn't.

Stockinette, as we've said, curls from side-to-side because it is wider on the front than the back, and curls from top-to-bottom because it is longer on the back than the front. Which kind of curl predominates depends on whether the fabric is short and wide, or long and skinny.

However, ribbing, garter, seed stitch don't curl at all--not top-to-bottom, not side-to-side. And this is because there is a roughly equal number of heads and arms on EACH face of the fabric.

Knit a couple of rows in a few of these stitches and you'll see for yourself that it doesn't even matter how the heads and arms are arranged, whether in alternating rows (garter stitch), alternating columns (ribbing) or some other pattern (seed stitch) (flat-knitted seed stitch, a.k.a. moss stitch=k1, p1 every row on an odd number of stitches). All that matters for non-curling is that there be a roughly equal number of heads and arms on each side of the fabric.

Once the numbers are equal, the fabric reverts to something more normal: it isn't wider on one side and longer on the other. Because they have an equal number of heads and arms on both sides, garter fabric, ribbing, seed stitch and other similar fabrics are equally wide on each side, and equally long on each side, so there's no curl. Long story short: Same number of arms and heads on each side of the fabric=no curl. That's all there is to it.

Why garter stitch and reverse stockinette look so alike.

Garter stitch is made by knitting every row back and forth. Now, as you know from the first little experiment, knitting pops the heads of the stitches out on the back of the fabric--away from you. If you make garter stitch by knitting back and forth--first one one side of the fabric, and then on the other--you're popping the heads out on ALTERNATE sides of the fabric, and the result is one row of heads is alternated by one row of arms. In other words, in garter stitch, you're not aligning all the heads on one side and all the arms on the other, as you do in stockinette--instead, as stated above, under the explanation of curling, you're aligning them in equal rows on both sides of the fabric.
click picture
garter st fabricAs to why garter stitch looks a lot like reverse stockinette, it's because heads are a lot more assertive than arms. Stated otherwise: knitted arms lie in meek, flat, unassuming little V's. Heads stick up--they are bolder, more three dimensional. Garter stitch puts heads on both sides of the fabric. True, garter stitch also puts arms on both sides of the fabric, as you can see from the drawing above, BUT like assertive types everywhere, the 3-D heads predominate --they capture the eye, while the meek, flat arms retreat from notice.

In reverse stockinette ALL the heads are on the face of the fabric, in garter stitch, only HALF the heads are on each face of the fabric. But because of the presence of those assertive heads in both garter stitch and reverse stockinette, both fabrics look alike, although they are made differently. To distinguish garter stitch from reverse stockinette, just flip the fabric over and you'll never be mistaken. Garter stitch looks the same on both sides, while reverse stockinette features smooth stockinette fabric (the arms) on the other side.

"Nothing but knit" and circular stockinette

Now we're at the final question. All the stuff above about head and arm alignment makes it possible to explain why "nothing but knit," done in the round, turns into stockinette, while done back-and-forth it turns into garter stitch.

You won't be surprised to hear that the answer, again, lies in the alignment of the heads and the arms. If you knit there and purl back, you already know that you're aligning the all the heads on one surface of the fabric, and all the tails on the other surface of the fabric. In other words, knit stitch (done on the front of the fabric) pops the heads back and purl stitch (done on the back of the fabric) pops the heads forward, so all the heads always end up on the same side--the back.

In circular knitting, you never work on the back of the fabric--you're always going around and around on the FRONT of a fabric TUBE. In other words, you never "turn at the end of the row" because there IS no "end of the row." There is only a never-ending spiral tube. So, in order to make stockinette fabric--in order to align all the heads on the back and the arms on the front, all you have to do is knit. One more time: knit stitch pops the heads to the back. So, if you stay on the knit side--the front side of the fabric--all the heads will only be where you popped them: on the back of the fabric, the inside of the tube (reverse stockinette).

The English purl stitch

This is fourth of a series on "how to make knitting stitches." Previous in this series are "The English knit stitch," "The continental knit stitch," and "The continental purl stitch." Please excuse the delay: the original drawings for this post were corrupted and it was d**ned annoying most discouraging to have to start over again. However, my friend and neighbor J.A. came over, and her hands are the model for the new drawings here, so thanks J.

step 1

(Above) Hold the standing yarn (standing yarn=yarn coming from the ball) in FRONT of the work. Keep it under tension with the first, third and fourth fingers of the right hand. Insert the right needle under the RIGHT arm of the "old stitch" at the tip of the left needle (green). Be sure the right needle passes IN FRONT of the left needle, as illustrated. "Dip" the right forefinger (dotted red arrows) to wind the standing yarn (brown) around the right needle (solid red arrow).

Uneven knitting, part 1: stockinette fabric--how to tame "rowing out"

The human eye is great at seeing even the most subtle patterns, and for good reason--for much of human history, survival depended on knowing whether that shadow might be ... a tiger in the long grass, looking for dinner!

For knitters, this means the eye immediately seeks out patterns in knitted fabric--an advantage if your sweater features lovely cables. But the eye's ability to pick out patterns is a disadvantage if your sweater features the Knitter's Bane: the "rowing out" of uneven stockinette fabric.

the knitter's bane--uneven stockinette fabric
Stockinette fabric is typically made by knitting across the front and purling back. If you knit at a different tension than you purl (a VERY common problem) your fabric develops those tiger stripes the eye is so well-suited to detect. The looser row (for most knitters, the purl row; but for some knitters, the knit row) pouches out and distracts.

Below is a three-part post attacking this problem. Part 1 lays out some traditional tricks. Part 2 shows some limitations on these tricks. Part 3 lays out a final trick--a maybe new way of thinking about the problem.

PART 1: TRADITIONAL TRICKS

Many, many tricks have been developed over the years to counteract the problem of uneven stockinette fabric. The four traditional tricks I've found best are laid out below.

Trick one:
Garter stitch and circular knitting

The easiest cure for uneven stockinette fabric is never purling. There are two ways to accomplish this: garter stitch fabric, and fabric made by circular knitting.

In garter stitch fabric, there is only knitting back and forth. There is no purling. Similarly, in circular knitting, stockinette fabric is not made by knitting there and purling back. Instead, it is made by knitting endlessly, round and round.

Accordingly, for garter stitch fabric, and for circular knit fabric, it matters not at all that your knitting differs from your purling. There simply isn't any purling.

Many clever designs exist for garter stitch garments, especially those created by the late, great Elizabeth Zimmerman. As to circular knitting, many things can be made in the round--hats, sweaters, socks, even square flat things like blankets and shawls can be made without purling by working in the round if they are started from the center and worked on circular needles.

Trick two:
Adjust the tension of your hands

A more challenging solution to differently tensioned knit and purl is to teach your hands to tighten up what's loose, or loosen up what's tight. To work this, you first have to figure out which way is looser, knit or purl.

Here's how: make some fabric, ending on a knit row, and leave the fabric on the needle. Lay the fabric on a table, knit side up. Dim the overhead lights, and slant the beam from an adjustable table lamp or flashlight to throw your fabric into relief. You know that the row on the needle was made by knit. The row below that was made by purl, the row below that (2 from the needle) by knit, and so forth. Find the looser rows, and count down from the needle to figure out how they were made--by knit or by purl.

Now you're set to mess around--to experiment. Can you increase the tension on what's looser? Is it easier to loosen the tension on what's tighter? Rome wasn't built in a day, and neither did you learn to tension your yarn in a day. Change takes time and attention. Plan to make a scarf. That'll give you plenty of length to fool with tightness and looseness, and you'll be able to see your results as the scarf gets longer. In the best-case scenario, the scarf ends smooth and even, and the problem is solved.

Trick three:
Different size needles

This trick is really an extension of the second. If your hands stubbornly resist your brain, if they continue to churn out stripy fabric no matter what you tell them, the next thing to try is tricking those hands into submission.

Your experiment with the beam of light already revealed which technique is looser--knit or purl. For this trick, arm yourself with a needle of a smaller size, then do the looser technique with that.

In other words, if you are working with a pair of size 6 needles, and your purling is looser than your knitting, take a size 5 needle to purl, and keep the size 6 to knit. Remember--it is immaterial what size needle holds the stitches to be knit, the finished stitch is determined ONLY by the needle making the stitch--the right needle. This trick lets you create the looser stitches around a smaller needle, making the looser stitches smaller, and therefore tighter.

It might take time to figure out this trick--your scarf might be quite long indeed by the end of the experiment. Also, I know knitters who must use needles TWO sizes apart to tighten up the loose technique, so if at first your fabric remains stripy, try, try again.

BTW: if you're making stockinette fabric by working back and forth on circular needles, you can work this trick by screwing two different size points on each end of the cable from an interchangeable tip kit.
Trick four
Pick yarns which hide the flaw

Novelty yarn is generally thick and thin and every which way. Who cares if the purl and the knit are different? Frankly, with most novelty yarn, its hard to tell if it was made by knitting or purling at all--garter stitch is the more usual method of creating a novelty yarn fabric. Handspun yarn is also commonly available spun "thick and thin." Variegated yarns (some of which are beautifully hand dyed) and tweed yarns both help hide undesirable fabric stripes with a randomly varying color pattern--the eye is fooled away from the uneven fabric surface by the undulating colors.

* * *

All of the above tricks unquestionably work. For many knitters, these tricks solve the problem for once and for all. If you've just started attacking the uneven stockinette problem, one of these tricks could hold the solution you've been looking for. But, at some point in your evolution as a knitter, you may have bumped up against ...

PART 2: THE LIMITATIONS OF TRADITIONAL TRICKS

Garter stitch: Avoiding purling altogther can become tiresome. Garter stitch is bulky and slow to knit-- it takes a great deal more yarn to make the same length of fabric in garter stitch than in stockinette. Also, garter stitch is not suited to sleek fashions. A garter-stitch T-shirt or halter-top might be a bit odd.

As to circular knitting: at some point, perhaps the short rows back-and-forth across the back of a sweater neck or a sleeve cap, that old purling is going to rear its head. Then where are you?

As to changing your tension: If you can train your hands, this IS the best solution. Yet, experience shows that, for many knitters, when you're tired, or when you're knitting on autopilot, the hands may stubbornly revert.

The different size needle trick might work for you--it works for many--but when you want to knit with a new yarn, the relationships between the needle sizes might change--you might need two sizes smaller instead of one, you might need one size smaller instead of two. To succeed as a two-different-size-needle-knitter, you're going to have to be extremely serious about swatching each time you try out a new yarn. If this is you, great, problem solved. But, hmm...well... many knitters aren't really THAT serious about swatching.

And as for the last trick--using wild yarns, well... just as there is a limit to the number of garter stitch garments one wardrobe can absorb, so you may find that there is also a limit to the number of novelty tops, rustic handpun garments and tweed or varigated sweaters.

The upshot? Each of the tricks above works, but each is potentially limited in some way. If the limitations affect you, if you've tried these tricks and remain dissatisfied, then, the best and most lasting solution, IMHO, is what I am going to call ...

Part 3: NEAR-STOCKINETTE FABRICS

nr st fab 1 br ribNear-stockinette fabrics are those which can substitute for stockinette fabric with no alteration to the garment pattern. Near-stockinette fabrics feature a subtle surface pattern of purling on the "knit" side. Hunt through a pattern stitch book--ideal is a small all-over pattern. These surface patterns work two ways: first, the pattern itself interrupts the stripe, and second, the pattern disguises any remaining stripy-ness by inserting another, more pleasing pattern.

nr st 2 croc skinFor substitution into a stockinette fabric garment, the near-stockinette fabric you choose should not alter the structural properties of the fabric. However, it turns out that stockinette can take quite a bit of alteration and not lose its basic properties --the stitch to row ratio, the tendency to curl, the direction of that curl, the weight, hand (drape) and bulk of the fabric.

speckled-purl


Another limitation on near-stockinette fabrics is to choose one which doesn't interfere with your garment shaping. Carrying up a line of knit stitches in a broken ribbing pattern is a lovely substitution for reverse stockinette in an aran sweater (see illustration of broken rib) but it can make decreasing for a set-in armhole challenging. A less linear, less insistent pattern, like crocodile skin or speckled purl would not raise that issue.

Don't conclude that the stitch patterns shown here are all you have to choose from--these three patterns are my particular "old standbys" for near-stockinette fabrics, but there are many, many others to choose from.

Chain selvedge a.k.a. "slipped selvedge"

includes a how-to
If you slip the first stitch of every row (or every last stitch--makes no difference) you will get a lovely chained selvedge--a big improvement over the lumpy bumpy edges much knitting exhibits. When the time comes for picking up stitches (for a neck edge or a front band, or around the heel tab of a sock) you will be glad you have lovely, even chains to pick up through.

Here is chain selvedge by the "slip the first stitch" method, in four illustrated steps.

1. (Below) Knit the last stitch of the row through the back loop (tbl), as illustrated.
click picture
chain selvedge step 1
2. (Below) Draw the new stitch (green) up onto the right needle (brown) with the right "arm" of the new stitch forward, as illustrated. Withdraw the left needle (blue), leaving all the stitches on the right needle.

chain selvedge step 2
3. (Below) Switch the needles in your hands. The needle which used to be the right needle (brown) has become the left needle with all the stitches on it, the needle which used to be the left needle (blue) has become the empty needle held in the right hand. With the right hand holding the empty needle (blue), DO NOT KNIT the first stitch (green), but merely slip it PURLWISE from the left needle to the right needle. Knit the rest of the stitches as you normally would, until you come to the last stitch. Repeat from step 1 through 3 for the length of the knitted piece.

chain selvedge step 3
4. (Below) If you have followed the above instructions, the slipped stitch should lie "open" as illustrated on the left.

--TECHknitter

PS: Note that if you choose to work a slipped selvedge, it is very common to add 1 stitch at each edge of your knitting (2 stitches total).  In other words, if your pattern calls for casting on 30 stitches, you would actually cast on 32, thus assuring that your slipped selvedge in no way interferes with whatever the pattern instructions are.  Naturally, if you look over the pattern and see that the edges are simply plain anyway, you could just work the slipped selvedge on the two edge stitches without adding. Yet, even in this context, many confirmed slip-stitches would go ahead and add the two stitches anyway, out of habit.
