here's a tutorial I found on the magic loop with 2 socks
I've worked strictly with dpns; but am about to start with 2 socks on 2 circs in the next week or 2; after I order my needles; but will experiment with larger ones (needles) in the meantime. Now having actually done either one I can't honestly say, but IMHO, it looks as though 2 socks on 2 circs would be easier than 2 socks at a time with the magic loop method. I was considering giving them both a go; but I am going with 2 socks on 2 circs; personal preference I suppose. That is...if I make it there bc I'm a die hard dpn sock knitter; but am willing to give the circs a chance ; I'll probably love them!
I don't know if there is a 'best' method, Becky, I, obviously started with dpns and with the cuff down; my socks that I begin tomorrow (hopefully) will be my 1st toe up, simply bc I enjoy the cuff down method. Look around a bit at the sites & tutorials & perhaps you can decide what appeals to you. Truthfully, as far as I know, there are more beginning tutorials and such with dpns and cuff down, that I have seen. Let me know and I will send you a bunch of links
