I've begun too many socks. Ravelry is dangerous that way. I can see many examples of completed projects made with patterns in my own library. I can see many examples of completed projects made with yarn like that in my own stash. These are only two cross-referencing features on Ravelry. Yikes! I want to knit knit knit knit knit knit! However, when I finish the 3 (more) pair of socks I have going, I will NOT begin any more for a while. That second sock is just a bugger. I do allow myself up to 3 years to finish a pair. Longer if I deem it necessary.
