I am new to Weavolution and come to you with a big question. A friend and fellow weaver gave me bags and bags of rug yarn. She was given this yarn by a tapestry weaver a long time ago. In going through this windfall and sorting into color families, I think I have some that is 100 percent nylon (there is a label inside the cone), some is a nylon/wool mix and some is all wool. I have just started making weft-faced rugs and would love to use all this yarn. My question is can I mix the different yarns without comprimising the look of the rugs? These rugs will be used on floors, and I know anything with nylon will last longer than I will. I want to make sure they will behave as a rug with just one of these fibers would. I would rather throw out anything with nylon and just use wool as the feel is so much nicer, but I also see that Jason Collingwood's rug yarn is 80/20 wool/nylon so I don't want to be too hasty. Does anyone have any thoughts on this? Thanks so much.
