I had thought that Ravelry was just for knitters, but I heard from a fellow weaver that there are weavers on there as well. So, I went to the site today to sign up. I didn't realize what a small operation it is - I'm very impressed, but also a little sad that I have to wait six days to receive my invitation to join. :-) I'm sure it will be worth the wait.
There is nothing in the FAQ about weaving. It mentions crocheting and spinning and dyeing and designing, but no weaving. Ah well - I suppose I'll just have to wait and see.
