Shortening knitted ribbing--part 3: alternative tricks for bind off

(Apologies for the delay in posting this last of the series. Real life has been intruding around here.) 

Summary to date:  So far, we've shortening ribbing knit bottom up by removing the excess ribbing (waste fabric) then catching the live loops, then operating on those to bind off a new bottom. Part 1 shows shortening and binding off K1, P1 ribbing (also called 1/1) and part 2 shows shortening and binding off K2, P2 ribbing (2/2). 

The bind off in both cases was done with an ordinary chain bind off--links here to the chain bind off on shortened K1, P1 ribbing, as well as shortened K2, P2 ribbing. 

Today we'll step back one pace to just before that chain bind off. Here is what the situation looks like with the excess removed and the loops caught on the needle, but no bind off yet worked.

Chain bind off is sturdy and reasonably flexible, but it is not the only choice. There are other alternatives to operate on these caught loops and that's today's post. 

• Added edges. In this class of tricks, you knit an edge of some sort onto the loops of the shortened ribbing (1/1 or 2/2) caught on your needle. TECHknitting has posted about these various edges in the past, and those links are part 1 of today's post. 

• Self-edges.  Ta da! This (new!) trick works only on the caught loops of shortened 1/1 ribbing, but it works a treat. With this trick, the actual loops on the needles become a new bottom edge without adding any more yarn.  Yes, strange as it may seem, it is possible to get a new non-raveling edge on your shortened ribbing working only with the loops you've caught on your needles in the shortening process--no extra yarn is added.  

Part 1: links to three added edges for shortened ribbing

You've removed the excess ribbing from your project as shown in part 1 and 2 of this series and now you have live loops on your needle as illustrated above. You can't bind off in pattern as you normally would because, just like a provisional cast on,  the stitches you've picked up are 1/2 stitch off the original pattern--you are picking up the tails of the stitches, not their heads. As we have seen, chain bind off does work, but if you don't care for that look, try these three alternatives.

A. Curled edge

An easy alternative to chain bind off is to simply work a few rows or rounds of stockinette, and then bind off using the same chain bind off featured in the two previous posts of this series.   Because of its structure, a few rows of added stockinette like this will curl up and hide the chain bind off, making a mysterious sort of curled up edging.  This curl, called "stockinette curl," is an undefeatable force of nature.  Although you knit it as a flat piece of fabric, have no fears, it curls permanently and will never flatten! This sort of edging is attractive, looking very much like an I-cord bind off.  

Here are the instructions for this curled edge, and here are more illustrations of a curled edge on various fabrics.

B. Fake I-cord (FICBO)

Another alternative is  FICBO--Fake I-cord Bind off.  Here are the FICBO instructions.  There is also a link to a short video (please click & skip the ads as soon as you can!)* The linked video shows FICBO on 2/2 ribbing. 

C. (Real) I-cord bind off

Finally, you can also work a real I-cord bind off. The linked post shows what that looks like.

Which added edge where?

As between a curled edge and FICBO, the stockinette curl edge is stretchier and lighter. The FICBO and knit-on I-cord look more polished, but are heavier: great for a hat edge or a front band, FIBCO and I cord may be too heavy for a bottom band. As ever, swatching is your friend. 

Part 2: Self-edge for shortened 1/1 ribbing--a new trick

On 1/1 ribbing shortened in the opposite direction from that in which it was knit, it is possible to make a self-edge along the bottom, meaning that, without adding any new yarn to the process, the new bottom edge is made up of the loops already caught on the needles in the shortening process.  In fact, with a self-edge, you actually have the opposite problem: you have to subtract yarn. 

When a K1, P1 ribbing is shortened by removing the excess rows from below the target row, (target row = newly exposed bottom row) the target row will not run out. As odd as this seems, it's true: the released edge cannot and does not form ladders like ordinary stockinette fabric, and the edge simply will not run out.  

So, hmmm....if these stitches are not able to run out into a ladder, is it possible to simply pull the needle out of the newly caught loops, leave the newly exposed bottom row alone, and NOT bind it off? 

Technically, the answer is yes. Once you've snipped a stitch and unraveled a row of ribbing in the opposite direction from that in which it was knit, 1/1 ribbing's non-running feature yields a structurally intact fabric. Therefore, no need to bind off because a picked out k1, p1 ribbing isn't going anywhere.

Aesthetically, however, there's a problem: the tension is all wrong. Unless tightened, the target row features a ruffled, wavy, messy, loose-looking edge. Ordinarily, at this stage, the loops would be on the needles, but in the illustration below, I have removed the needle and mildly stretched the fabric as would happen by simply handing it. I think you can see the problem with ruffling and looseness. 

If you take the needle out of shortened 
1/1 ribbing, the loops won't ladder out,
but the resulting edge will ruffle and spread

Putting this all together, theory dictates that to have an attractive edge, all you'd have to do is move the slack out of that bottom row. But...with a trick this conceptually simple, you just know there are catches, and here are three: 

• First as stated above, this works only in 1/1 ribbing, and only if the ribbing is being shortened in the opposite direction to that in which it was knit.  (The knitting-geek reason is because when you're working upside down in 1/1 ribbing, each column you pick up is technically composed of the tail connecting 1 knit arm and 1 purled arm.  When each arm "points" a different way, the fabric is impossible to run out. With 2/2 (or higher) ribbing, the edge column is also half-and half, but the middle column of each rib is not.  Instead, the middle columns are one knit arm + another knit arm (which equals one whole knit column) or 1 purl arm + another purl arm (which equals one whole purl column). As we know, knit columns and purl columns  run out very well, so simply tightening a column like this will do nothing to prevent running.) 
• Second, the loops still have to be on the needle for this trick to be worked.  If the loops have fallen off, it's unlikely you'll re-seat them prettily on your needles, so you'll have to get pretty new loops by catching the stitches of the row above the fallen-off loops. 
• Third, if there's a split stitch or a halo-snag anywhere along the run, the slack in the yarn can't be transferred from one loop to another. This trick works only in a smooth yarn, smoothly knit. 

A "halo-snag" is when you're knitting a yarn with a halo, like mohair, and you knit through the "halo," or fluff of an already-made stitch while you're knitting.  With fuzzing yarn like this, the error is usually to catch the running yarn not just under the loop of the stitch you're knitting into, but also to catch the yarn through the halo of that stitch, or sometimes through the halo of a neighboring stitch.  If you're lucky, you can see where the halo-snag is located and cut loose the fluff of the halo without cutting into the underlying yarn, but generally the trick of pulling slack out of a snipped ribbing is harder to do with a halo'ed yarn.

With a split stitch, you could, theoretically, cut loose one or the other halves of the split, but this weakens the yarn.  If the split is minor--one ply of a four ply yarn, for example, or a small fraction of a robust single-ply yarn like a lopi, you may choose to CAREFULLY cut the split loose, but if the split is major, your best bet is to re-target: move up a row, remove the row with the split and hope the new target row doesn't also have a split. 

However, once you've gotten past these problems: once you have the 1/1 ribbing loops on your needle, and you've examined each and every loop to make sure it moves freely, here's how to pull out the slack and make a nifty self-edge along the bottom of the now-shortened ribbing.

Step 1 (below): locate the lowest edge stitch which is FURTHEST from the tail.  The red arrow shows this loop located and dropped off the needle, waiting to be operated upon. 

Step 2 (below): pull the loop of this stitch out until it becomes larger, as shown by the red arrow. How much to pull out is a matter of trial and error. You do not want the edge too tight, so when going up the learning curve, err on the side of too loose: you can always return and pull more slack out. 

Step 3 (below): Switch to the next stitch (red arrow) then repeat pulling out the slack (blue needle).

Step 4 (below): As you work your way leftwards along the stitches of the target row (red arrow) you can see that the loop of slack gets bigger and bigger, and the tightened edge begins to look mighty fine.

Step 5 (below): The final result--looks a lot like a tubular cast off, doesn't it?  (And, although there is no "tube" has been made, this self-edge yarn does take a very similar path along the bottom edge as it would in a tubular cast off.)

--For the record: it was a situation in Ravelry techniques forum--where the knitter had popped off the ribbing without catching the stitches--which inspired this series of posts.
