When knitting cables, these little cable needles are one of the best aids to success. The birch wood has a very slight toothiness to it, which helps keep the cable needle from sliding out of stitches. The length is long enough but not too long. And—the part we really love—the center of each cable needle is slightly narrower than the tips. This subtle tapering helps keep the stitches in place as you make your wonderful, amazing cables. The set contains one each of sizes small, medium, and large, each measuring 3.75" long.
