The Knifty Knitter straw weaver made by Provo Craft is not so much a knitting loom, as it is a weaving tool. If you've seen them, but you aren't quite sure how they work, this page is for you. Below are instructions for using the weaving tool, project ideas and information on where you can buy them. The straw weaver tool comes with a metal hook, a yarn needle, and a clamp. It works best with medium to bulky weight yarns. It is very useful for making woven belts and you'll find the free pattern to weave a belt below.
