I've actually never knitted socks before.
GG is right, though, any yarn will do. I just love how colorful this is. I may just need to start collecting sock yarn
The sweater I'm working on is so complex, except for a few very short sections, the cable is worked every other row, and I'd really like to finish it before I move on to something else, especially after reading about ArtLady's misadventures.
