I am knitting a cowl on circular needles, After knitting 40 rows it is apparent that i twisted the cast-on. Now I would like to undo the twist and thought I would steek the piece, untwist it and sew the seam closed. Help.
Sure you can do that. Sew a line of stitches along either side of where you're going to cut so it doesn't unravel.
Or just start over.
