I'm a relative beginner working on a pair of longies. The pattern tapers in the bottom of the leg & has a ribbing cuff. How do I go about altering the bottom to make them slightly flared with a flat, straight bottom edge - what's that stitch called - so it doesn't get folded up or go all curly. I'm just past the knee on the first leg, knitting on straight needles (not in the round).
Hope someone can help.
