i make hooked wool rugs, locker hooked rugs, wrapped clothesline rugs and even crocheted rugs...I LOVE RUGS! almost more than quilting (did i really say that???)
but i don't have room for a loom- or the desire to start yet another different technique---so- i sold my loom
i suggest you visit the place offering classes- and ask questions about looms- the one i had was a table top loom-not real big- but for some reason very expensive (at least i thought so) my mom had picked it up at an auction and given it to me- i moved it from spot to spot for about 10 years- then decided it was just in the way- when i finally decided to look it up and find out about it i found out that they sell for anywhere from $400= $750 for the one i had!!! it deserved a better home than what i had been giving it! so i let it go
rag rugs are seldom (if ever) made with a loom
rag rugs tend to be hooked- or crocheted- or tooth brush rugs---which is another technique- easy to learn- easy to make- uses up those scraps!
prehaps do a rag-rug search
