If you go to the link mentioned above, you will see how they do two socks on two circulars. Much easier than DPN's in my opinion. I think I did do two socks a long time ago on two circulars but I don't remember now how to do it. But I want to do two sleeves on them now. It's not really complicated once you have cast on and get going.

Sounds pretty complicated.
