I am new to weaving, I am going to try to 'dress my loom' solo. lol I was given some carpet warp. I would like to try to make a 'Samplier" of differnt weaves, I don't know what to use for a weft. I would like some suggestions, please. I did make a couple of placemats, using cotton that I purchased to crochet dishclothes with. they turned out pretty, I don't think tho it would show up the samples very well. thank you for your advice.
