Hello every one, I am knitting a plain stocking stitch two ply shawl for the expected fourth grandchild, and want to crochet round the edges to finish it off nicely. Didn't want to follow a pattern so I could just knit without concentrating and watch telly at the same time, as it is quite a size and slow going. I love how soft and pliable two ply knitting is for new born babies, but I'm not sure what size crochet hook to use. Is there a way of knowing? I am using size 3.75 knitting needles and, as I said, 2ply wool, so the knitting is quite loose. I don't normally crochet but feel I could manage a little border. Will need to think about the corners though. Any ideas please?
