CROCHET - in my opinion, the most versatile of ways to work with fibers.
Crochet is the technique of pulling loops through loops with a hook to make chains and ropes, fine laces, flat fabrics for blankets, clothing, and rugs, baskets and three dimensional shapes, and jewelry. Almost any flexible matierial can be crocheted - threads, yarns and other fibers, fabric strips, plastics, metal wire.
