I can understand picking up stitches when your yarn is still attached to the project, but I've got a dilemma. I'm knitting a bootie (they're kinda like Mary Janes) from a book called Instant Expert: Knitting (Ros Badger). It gives directions on making the body of the bootie and then sewing it all up and then for the strap, the directions start with:
With RS facing, k18 sts at heel (9 sts at each side of joining), then cast on 14 sts.
Umm...how am I supposed to k18 sts if I've got no live sts? I've bound off the whole thing and sewn it up! So my question is, how can I pick-up sts from the cast off edge when my yarn is no longer attached to my work?
