I have this book as a guide in case I get stuck:
It's a very handy book and comes with a bunch of patterns too! If you are doing a fairly simple pattern, this really is the way to go for knitting socks, IMHO. You don't have to worry about making notes on how long of a heel flap you did, how many inches of ribbing there are, how many stitches you have decreased on the toe, or anything really because you are knitting them in tandem and what you do to one, you do to the other on the same row. It's the same amount of knitting, obviously, as doing them one at a time but for whatever reason, they seem to knit up so much faster this way.
