Someone emailed me tonight asking for information about knitting socks on circular needles. I thought, "What a great question! Maybe I should put some links on the blog!" Soooo that's what I am doing. Here are some links regarding socks on circular needles. I hope you find them helpful.

I would have found more, but I'm too tired. I'll try to look for some more tomorrow :)
