Fastening long floats for invisible stranding--alternatives to the STUART ladderback

Invisible stranding in color knitting via ladderbacks has been the topic recently.


Today's post goes shows alternatives to STUART. STUART regulates tension: it's a way of breaking up long floats by temporarily parking them on the fabric face. But, if you are an expert knitter (or just a bold one) you could simply knit super-long floats without any tension-regulation help, then tack down your super-long floats afterward, as part of the finishing process.

Today's post does not talk about how to KNIT those floats--it simply shows you three methods for TACKING DOWN those long floats as part of the finishing process.


Alternative #1:  TACKING also called FREE-FORM PINSTRIPE
(column-in-a-column, similar to the quilter's trick of "stitch in the ditch")
The previous post combined STUART with  pinstripes : it showed the catchment column re-hooked as a PURL column, and then a pinstripe was worked up this purl column to tack the long float in place, row-by-row.

However, It is actually possible to work a "free-form pinstripe" right up the middle of a KNIT column, and use that to catch the floats on every row. Despite that pinstripes are ordinarily worked into a purl column, a purl column is not actually required. Instead, you can work a pinstripe in a different way--worked right through an knit column--and tack long floats in that manner.Working a pinstripe through a knit column is called "tacking,"or "free-form pinstripe." It is the knitter's analog to the quilter's trick of "stitch in the ditch."

Here is a diagram of what is going on.


tacking, also called free-form pinstriping, in action

Here's a close-up of what's going on:


close-up of tacking

The blue stars point at the blue-dotted stretches: these are the running yarn behind the slip stitches.  It is these running yarns which hold the floats (red) against the back surface of the fabric. Naturally, the slip stitches and the background stitches would be the same color in real life (photo below). I just drew the slip stitches white and the background stitches gray so you could see what is going on.

Below is a photo of this process in real life, using tacking yarn of the same weight as the background stitches. 


Column-in-a-column free-form pinstriping, in real life. Blue colorization highlights left arms of the original stitch, green highlights right arms,  red highlights the free-form pinstripe-tacking

You can see the white free-form pinstripe forming a column-in-a-column on the fabric surface. The original knit column is split in half by the tacking.  The left arm of the original column (colorized blue) frames the centered free-form pinstripe (colorized red) while the right arm of the original column (colorized green) frames the right. The bottom part of the photo shows the free-form pinstripe in its un-colorized state. As you see, it's subtle, even on extreme closeup.

Here's the back view. The white free-form pinstripe tacks the long floats (black) to the back surface of the fabric on every row.


The white column-in-a-column free-form pinstripe, as seen from the back, used to tack down long black floats on a white background

Are you concerned that this column-in-a-column tacking will show or be bulky? If worked in a thick yarn, as here, I'm not going to lie, the answer is yes. You can both see and feel the tacking column. In fact, if you use this trick, then as the knitter who made the thing, you will never be able un-see it.

However, this does not mean others will see it. See, you have to convince yourself, just like magicians do, that despite how obvious this looks to you, it is invisible to others. "Magic tricks" work because people only SEE what we are LOOKING for. This trick doesn't disturb the fabric so much that it draws attention to itself. Despite knowing something was up, none of the knitters in a class I taught caught this on first sight, and only two out of 10 noticed after being allowed to handle the original sample and look at the outside. Naturally, once they could look at the inside, once the matter was brought to their attention, it was head-slappingly obvious. However, if eight out of ten knitters did not notice despite handling the material, I believe you may rest easy.

Naturally, the thicker the original yarn, the less likely this trick is to escape unnoticed, but the photographed sample was knit in worsted weight, the tacking was worked in that same weight and the whole business still slipped by some fairly knowledgeable folks. 

Geek note #1: ALMOST INVISIBLE IN A THINNER YARN
 It's possible to work this trick with matching yarn which is much thinner. The easiest way to get a perfect match in thinner yarn is split out a ply. A future post will show yarn-splitting, and a link will be placed here at that time. This trick of using thinner yarn makes tacking almost invisible.

Geek note #2: POLYESTER SEWING THREAD
Tacking with a thinner ply is almost invisible, but tacking with sewing thread is utterly and truly invisible. Even as the person who made this, you can't find it. With this trick there's only a photo of the back because there is literally nothing to show on the front. 

Ordinary black polyester sewing thread used instead of yarn to tack, where the surface fabric is black (in other words, what is being caught here is long white floats behind a black background).  The thread is invisible on the front--which is why the only photo is of the back!

But, if this is so invisible, why is this not the main method for tacking down long floats? Couple of reasons. First, tension is more of an issue with thread than with yarn. Second, sewing thread is so strong that, with wear, it might cut the yarn fibers, especially cashmere, merino or other soft fibers. But the main problem is that sewing thread is slippery and hard to slip-stitch with. It's frustrating to lose the thread-loop and have to start all over again (and again, and again). You can (somewhat) mitigate losing the loop by working with a small latch hook, like a knit picker, but the tension problems really arise from trying to control the loop in the first place. A truly invisible as this is, it's waaay pickier than working with yarn, and working with yarn is plenty picky already.

Geek note #3: The photos and diagrams above show the float running free, then tacked down via a free-form pinstripe.  However, if you find that your floats are a bit loose, you could ladderback the floats and THEN tack them down. In other words, you don't have to STUART-ized your long floats (slip and park, the release them)  to afterward form a ladderback, you can actually simply ladderback ANY long floats which were knit with enough slack to avoid puckering (the trick, however, is to knit looooong floats at a perfect tension--which is quite a trick!)

Geek note #4: You could try running the free-form pinstripe tacking BETWEEN the columns, but I think this is more obvious--it appears as an extra column inserted into the fabric, per below photo. However, this might be a trick to try if tacking near some shaping, where columns come and go due to increasing or decreasing.


...appears as an extra column inserted into the fabric...

Alternative #2 DUPLICATE STITCH
Rather than tacking in continuous columns, you could instead use duplicate stitches to tack the floats, either a) every-row, or b) in bunches. If you do this trick, then, like all duplicate stitching, be sure to duplicate stitch with a dull-pointed needle so you don't pierce the floats or the fabric stitches on the outside, but actually work over the fabric-surface stitches, as well as the floats.

a) Every row
If you work a duplicate stitch every row to fasten down the floats, ask yourself why you aren't freeform pinstripe-tacking instead? Pinstripe-tacking is worked with a running yarn (faster) while sewing (which is what duplicate stitch actually is) is worked with a cut-length (slower). However, perhaps you prefer sewing duplicate stitch to slip-stitching a column with a crochet hook? If so, carry on...  

b) Bunches
If you gather the floats into bunches on the back, you'd only have to duplicate stitch every few rows.  This works best if you only have a very few rows of floats to gather up (two floats? three?)

And think how neat it would be if you actually used the duplicate stitch to not only tack the floats, but as a pretty little highlight-stitch in a completely different color--a dot along a Fair-Isle row, for example, thus killing two birds with one stone. This little samples hints at the possibilities.

Below shows the sample front and back after knitting, but before tying the long floats down with a duplicate stitch.


Below shows the front and back during the duplicate stitch process.


The obvious downside to duplicate stitching is more ends to work in. However, in the above sample, ends are minimized by having the yarn skim from place to place. Which leads to a final trick...

Alternative #3: SKIMMING
Simply skim down super-long floats without the duplicate-stitch trick. For skimming, thread a sharp sewing needle with a sock yarn or a split-out ply in a matching color, then skim though the floats and the fabric back. This is just like skimming in ends. It doesn't look that great on the back (but it doesn't look worse than the duplicate stitch, either). Skimming is a straightforward way of fastening down super long floats invisibly: much better than leaving super-long floats on the fabric back.

Long floats in color knitting: modifying STUART ladderback jacquard for rough-use situations

The STUART long-float method, which I recently introduced, showed how to tame long floats in color knitting.  That was followed by a gallery-post--a photo essay showing the STUART method used to knit a long float hat. Today's post extends the STUART theme by showing modifications for making the ladderback tighter, as well as for tacking it onto the fabric-back.

Why would you want to tighten the ladderback, or tack it down? Well, the ladderbacks of a ladderback jacquard are almost like a separate layer of fabric, loosely lining the inside of the garment.  In a hat, this loose arrangement is generally no problem: heads are covered with slippery hair.

However, the situation is quite different where a ladderback item is designed to fit tightly or where it could get caught on a sharp angle or a protrusion--a finger in a child's sweater, the spout of a tea-pot in a tea cosy, for example.  Or--today's example--a hot water bottle cover.



Hot water bottle cover, outside and inside--note the tight ladderbacks

I knit the above sample because hot water bottles are the ultimate in hard-to-dress items. They are made of a grabby, almost sticky rubber; they have two-sharpish edges; they feature a small flange on the bottom--in other words, they feature lots of stuff for floats to get caught on.   Aaaaaand, to make dressing the hot water bottle even harder, I designed this cover with two large snowflake motifs, widely separated--one on the front and one on the back.  This means the floats don't touch down anywhere between the snowflakes, but instead have to go a lo-o-o-ng way, around a 180 degree bend, to get from place to place.   This design features 11 rows of 26-stitch-long floats.   I think that if you can get a knitted cover--featuring super long floats which go around a corner--onto a hot water bottle, you can pretty much be assured these floats can handle anything.

The opening photos shows the cover relaxed, but this one below shows it in action.



even when stretched, the floats do not show through on the front...


...and the floats do not show through on the side-panel, either

I deliberately over-exposed the side-panel photo so you can really see every stitch of every row and column: see for yourself that with STUART, the floats simply do not show through at all, even when the cover is stretched.

But going beyond the invisibility of the floats, you can see that this cover is laying smoothly over the grabby hot water bottle.  STUART by itself would not assure this result: it is the modifications shown in today's post which help this cover to lay as smooth and flat as it does.

Herewith, the two tricks of today's post: 1) anchoring the ladderback with a twist, 2) pinstripe-tacking the long floats into place alongside the catchment column.


* * *

Trick #1: TIGHTEN the LADDERBACK by ANCHORING with a TWIST

This trick assumes that you are at the point in the STUART process where you are getting ready to hook the ladderback up along the back of the fabric.  In this trick, rather than simply catch the second strand loosely under the first--as is normal with STUART,  I instead put a backwards twist into the bottom rung of the ladderback, then drew every subsequent float through, sequentially.  The red circle indicates the back-twisted stitch.


The red circle highlights the twisted anchor stitch at the bottom of the ladderback. This twisted stitch forces the rest of the ladderback into a narrow, tight column. 

Also notice that I used a short float from the row below the ladderback to anchor the initial twist.  Anchoring the column of the ladderback by starting the first float with a twist creates a tight single-column ladder, rather than the loose triangle typical of STUART ladderback construction.

In some situations, a twist-anchored ladderback might be enough in itself to tighten the floats down--perhaps at the left and right edges of a circular-knit sweater.  However, where the float has to actually wrap around a sticky corner, such as in this hot-water bottle cover, the twist-start column is best used in partnership with the next trick--a trick which actually tacks the ladderback, row-by-row, onto the fabric back.


Trick #2: PINSTRIPE-TACKING: use a PINSTRIPE to TACK the LADDERBACK onto the FABRIC BACK

The point of this next trick is to fasten the ladderback, row-by-row, onto the back face of the fabric. In this way, the ladderback is no longer a loose inside layer which can slide around as you put the garment or item off and on.  Instead, the ladderback becomes one with the fabric. This prevents the sliding ladderback from distorting the stitches in the fabric which they would otherwise pull on, every time the ladderback itself was pulled up or down.

The basis of this trick is really quite simple: I used my pinstriping trick to tack the ladderback onto the fabric-back, row-by row.   Here are several photos of the result.



The black chain of stitches represents the running yarn from the pinstripe on the fabric surface.  If you look closely, you will see that I messed up in several places, catching the floats in the wrong order.  No big deal, however. 


This close up shows the details: the black chain stays to the same side of the tight ladderback and never crosses it. Therefore, the ladderback was worked slightly off center

Here's the step-by step:

  • I used the STUART method to slip the floats.  
  • Continuing in the STUART method, when it came to release the catchment column, I released an entire column of the black knitted fabric to the level of the first float. 
  • However, rather than hooking this black fabric up as a knit column, I hooked it up again as a purl column instead, as shown in the pinstriping post.   
  • Next, I hooked the ladderback up--the white floats, I mean--starting with a twist, as shown in the first trick of this post.
  • Then, working from the fabric-front, I worked a black-on-black pinstripe over the purl column.  
    • As I worked each slip stitch of this pinstripe, I carefully peeked to the back with each stitch, and caught the corresponding float behind the running yarn.  
    • In other words: I used the running yarn of the black pinstripe slip-stitch to tack each white float onto the fabric back, working stitch by stitch (row by row).  

The upside of pinstripe-tacking is that you can now knit with floats as long as the Nile: the floats will be at the correct tension AND they will never catch, either.

However, as we know, there is no free lunch in knitting--there are some downsides: first, this is fussy. It would be particularly fussy if you were trying to work inside of a long narrow tube like a sock, because you have to keep peeking from the front to the back of the fabric with every single slip stitch of the pinstripe column.  (Maybe design your socks so the ladderback is on an accessible portion of the garment: the foot on a toe-up sock, or the top of the leg on a top-down knit sock, then work the tricks before you knit the rest of the sock.) Second, you can kind of see the pinstripe if you really look hard: scroll back up to the previous photo of the side-panel close-up, the pinstripe does reveal itself as a (rather  minor) irregularity in the column-tension. Finally, you can also feel the pinstripe--the fabric is double thick at that point because the pinstripe adds a layer over the purl column.

In my analysis, the advantages outweigh the disadvantages. These long floats have been turned into a ladderback securely fasted onto the fabric back on every single row--this ladderback is going nowhere, no matter how roughly it is treated and no matter how long the float is. Long floats can no longer be caught by accident so they distort the fabric.

And speaking of float-length, let me point out that although I tacked the ladderback onto the fabric back only along the "side seam,"  I did actually create more slips and ladderbacks.  Here is a photo of the cover's inside, showing that I ran STUART slipped catchment columns alongside the snowflakes, and between the top and bottom parts, also. If you want to see more what I mean, scroll up to the opening photo and examine the right panel--you'll see three ladderbacks, but only the middle one (the one along the "side seam") is actually tacked down with a pinstripe.


The catchment columns around the giant snowflake motifs (not tacked down) 

* * *

Conclusion: armed with STUART and today's modifications, I believe we may celebrate the downfall of another knitting rule.  STUART (or any ladderback jacquard technique, actually) lets you knit floats as looooooong as you like.  Today's tricks let you adapt ladderback jacquard to rough service items like hot-water-bottle covers, blankets, children's sweaters, and any other item where you thought a long float or a loose ladderback might catch on something.

Warning: Politics

For 10 solid years, TECHknitting has always been about pure, straight up knitting. Well, not today. Fair warning: if you want knitting, wait til the next post (which will be more about the STUART method) or read through the archives.  Today, TECHknitting is a personal letter from me to those who voted for Donald Trump.  If you're too young to vote, voted for anyone else, didn't vote, live in a different country, with all due respect, this letter is not for you.

* * *

Our country just elected a hard-headed businessman as the president of the United States, a man who claims great wealth.  Under his guidance, we are now to get rid of health care for those who cannot afford it and we are to slam the door on refugees. The sick, the persecuted are no longer to be offered our help, they are on their own. Our president-elect has repeatedly made this clear.




We, the formerly proud country which led the world by example of how everyone could get along just fine--founded on the idea that a farmer would stand equal to a nobleman; we the country which welcomed and held out our hand to our neighbors and the poor among us--the richest country the world has ever seen ...well ... we are no longer to be a light unto others, no longer a nation of sharers. Your vote declared our tank is dry.

Fine.  OK.  Fine.

You voted for Trump, you knew what he stood for, you agree with this result. So, here's the deal: You voted for a new day, sister, and I'm here to tell you, in my own small way, that you can now live in the world that you voted for. I've been thinking about this since last Tuesday, and I'm not willingly sharing anymore either.  If you voted for Trump then you do wrong to go on using TECHknitting blog.

Who will enforce this? You will!

See, if you believe in your heart that each person among us must find his or her own way with no free help from you, then you know in your heart that you don't need any free help from me.  Those who do not believe in free gifts--do you recognize that I mean you?--should not take them.

Do you feel punched in the stomach by my remarks? Do you feel betrayed? Have my remarks ruined TECHknitting blog for you?

Believe me, I feel punched in the stomach by your vote. You have voted a mean rich man onto the throne of judgment on the poor and the wretched. And if you think it's OK, because sometimes you have to take the bad with the good, and he will be the savior of you or of our country, you know that can't be: no savior ever came dressed in hate.

Yes I closed the comment section, no I don't want to hear it. You allowed yourself to be led astray against your own better judgment, and there is a consequence.  Sadly, this little pinprick from me will be the smallest and the least of it.

Ten years of TECHknitting

Ten years ago today, I read a knitting blog and thought to myself "I could write a blog, too..."


Thanks for reading TECHknitting blog--TK

Zippers in knitwear, the no-sewing way, update!

In 2010, I wrote an article in Interweave Knits about installing zippers into knitwear, a new non-sewing way. In 2012, I wrote an illustrated blog post about it.  There's also a video about the method.

This no-sew method involves turning a zipper into a "knitable object" by  using a knit-picker (a tiny latch hook) to basically YANK loops of knitting yarn directly through the zipper tape. These loops are then attached to the front bands of your sweater just like you would attach any other strip of knitting: by 3-needle bind off, or any other method you like. "No-sew zippers" is one of the most popular posts I ever wrote, but today, there is an important update about the method.

In a marvelous new development, Dritz (the notions company) has evidently invented a zipper with a purposely loose-woven zipper tape, so you can pick your stitches up directly through the tape, using an ordinary crochet hook.  The below photos are screen-grabs from the Dritz website--


The Dritz website shows a new loose-woven panel which lets you pick up loops directly through the zipper tape itself.  Since you can do this at the perfect gauge for the adjoining fabric, the zipper ought to lay nice and flat.


With the loops picked up, the zipper has become a "knittable object." You can attach the zipper to the front bands in the same way that you would attach any two pieces of knitting together: three-needle bind off, etc. 

So, if you've ever needed to install a zipper in a sweater, have a look at the linked TECHknitting blog posts above, BUT order one of these new zippers (I found them available on-line) and realize that you can forget all about that business with the knit-picker! Amazing. And even if it turns out that picking up the loops with a knit-picker works better than a crochet hook (just because of the latch feature of the knit-picker) it would still be way easier to work through a loosely-woven tape than a stiffly-woven one.

Just so you know? I get nothing from the sale of these, and don't know anybody at Dritz either.  I simply think this is a marvelous (and newsworthy!) advance over my original method. Why struggle with a stiff tape, when a zipper with a much looser tape is available?

Go add a zipper to something, OK?
