I LOVE this vest! It's truly one-of-a-kind. Made with a variety of yarns, the designing is up to you. Great for using up your stash! Change yarns and patterning throughout vest. For instance, use moss stitch, stockinette, garter or knit some new pattern you've been wanting to try. It can be made short, long or in between. Uses size 9 needles. Available as a kit also.
