I have completed the second legwarmer, and it is successful. I did one of the stretchy bind-off techniques that Mmario linked me to (k2tog tbl, slip stitch back to left needle, repeat until all stitches are bound off), and I also increased my needle size just for good measure. It fits like a charm...now let's just hope whomever purchases it has the same size thighs as me. LOL Regarding the previous legwarmer, the de-bind-off is going well, I think. I realized after the first 14 stitches that I was only undoing the "psso"'s, but not un-knitting and un-purling that row's stitches. Oh well. No biggie. I think the important thing is that I can get it undone and then re-bindoff appropriately.
So I am on the cusp of finally completing the legwarmers. They ALMOST became a YSP, but I refused to let them cross that line. Up next? Alligator scarf!
