My mother-in-law showed me how to make "hooked" rugs out of old WOOL clothing/coats. She cut the cloth into narrow strips and "hooked" them through burlap. I think that she bought the burlap at the store and drew her own designs on it with some sort of marker. They were very vintage looking - mostly dark colors because they wore dark colored clothing/coats, etc. So, I started buying wool clothing at yard sales, Goodwill, etc. - easy to find back then - about 45 years ago. I cut them into strips and did make one decent looking rug. I had a huge box of strips in my utility room and we had a water leak and the box soaked up all of the water and sat there for a long time before we discovered it and so had to get rid of all of my wool strips. I thought that I might make a hooked rug out of polyester double knit strips but never did.
