I bought an old brand new in the box Erica 25" loom. (only $5.00!) It was made by the Northfield Loom Co & is, apparently a "rigid heddle frame loom." I haven't even assembled it yet. The manuals with it are dated 1975. Anyway, I have NO experience or knowledge, other than remembering my grandfather making rag rugs when I was a youngster in the late 60's. So, the manual calls for warp made of cotton carpet warp or crochet thread, and the weft 4 ply knotting worsted or rug yarn such as rya. Where do I get something like carpet warp? By crochet thread, do they mean the stuff that people were all big about knitting their own dishrags with ? It's aLOT heavier than sewing thread, but not as big as yarn? Can't think of the brand, but this was probably 15 years ago, comes in spools about 4" across & 5" tall? With the weft, should I be looking for cotton yarns, or could narrow cotton cloth strips work, and if so, anyone have a ballpark idea of how wide to cut...1/2"? If I am planning to make placemats/runners, are these materials still OK? Is this loom a good beginner piece? Any advice, books, resources to recommend that I might find helpful? Sorry for the barage of questions. I need to figure out lots before I'm ready to jump in...a calculated guess kind of person.
