Method for cutting old clothing or fabric into strips for rag rug. Lots more at link including this tidbit: "Even cardboard and paper, when made into strips, can be woven." via "Handloom Construction: A Practical Guide for the Non-Expert"
A no-sew rag rug, awesome! I'm currently weaving a t-shirt rag rug on a hoola-hoop, but I'd love to try this technique next as I can make the rug as big as I like (not as big as the hoola-hoop allows) =D
