I am starting a pattern for slippers that requires short rows with wraps and turns. O.k. I’ve watched Amy’s video and read a couple of written descriptions of W&T. I think I understand how to do it. I do have a couple of questions. First, should you always do a wrap when you are knitting a short row, or only when the pattern specifies it? I have knitted quite a few socks since I started knitting about a year ago, and I have never wrapped the stitches before turning. Have I been doing it wrong all this time? What is the purpose of the wrap? :??
