I’m new to weaving textiles (I’ve woven rag rugs for years). Does it work to weave a weft-faced wool rug with a cotton warp? If so, would I use 8/4 cotton warp as I do for rag rugs? I’ve never woven with wool–what weight would I use? is there a brand that Jane carries in her shop that would be recommended? I can look up the sett for a weft-faced rug but appreciate advice for anyone experience with weaving weft-faced wool rugs. Thanks in Advance!
