I went to my search engine and typed in "knitting looms" ...
Bev's Country Cottage is an amazing site of how-tos, crochet, knitting, sewing with thousands of patterns, links, and a heart to share
The decor Accents, Inc ... is a premiere site for wooden looms, my goal is to own an infinity board ... it will make an afghan that is is 60 inches wide ... and has a LOT of videos to whet your creative abilities on the loom.
