I knew I was going to mangle that explanation, but without pics it is a little hard to explain. If you have a section of knit cord in front of you, the end is made up of looped stitches, and there should be the tail of the cord you are knitting with. The trick is that you can make the stitches any size you want. With the lucet they al end up being about the size of the upright pegs - with needles it's your needles diameter. Once they are formed though, you can stretch them out to any dize you want just by feeding in some slack from the loose end.
If you picture your lucet cord as ending in two stitches (one for each upright), the end of the cord at any time before you tie everything off is made up of two small loops and the loose yarn. Stretch those two loops out and you get two BIG loops and a loose end.
A trick that you can use to increase the number of cords when you are working with loops is pass the big loop (you'll want to stretch it out to about 4 times longer than your final split pocket) back through the small loop in the row behind it. (I'm losing people here again aren't I?
). Folded like an N. All of a sudden you have *three* big loops, that you could braid like a balearic pocket if you wanted. On the other side, you'll have three loops and a spare strand - I'd just tuck that one in and braid with one group of 3. If you are weaving, use the tail as your weft.
The knit cord doesn't stretch at all once it is set. I'm using nylon twine.
