Cable poncho - this is a retail item ~ two rectangles, stitch to desired arm opening ~ stitch to form shoulders leaving a collar opening. pick up stitches for generous rolled collar . co slightly loosely! Hmm think this is doable!
There is no mystery to this gorgeous wrap, just a simple twist. You work it as a rectangle, then create a Möbius strip by rotating one end 180 degrees before joining it to the other end. Also has video on Tunisian Crochet hook and stitches
