Silver's sock tutorial is great and I'm sure that you will learn all that you need from there. But, if you are like me in any way a bit of visual help often helps, too! I have the DIY network and watch the show "knitty gritty" and this episode
is the one what made
the light go off over my head for me to figure socks out!! Of course, the entire episode is not at the site, but short video tutorials are!
There are also some sock videos here
