Thanks everyone! I have them on my feet right now!
I used a 9, but I knit loose so I should have gone down a size or two and adjust the pattern. Socks that are knit too loosely don't wear as well. I used bulky yarn so they'd be extra warm since I get cold feet.
Definitely learn! I didn't use DPNs for these, I used two circular needles. I find that they are easier to keep from getting ladders between the joins and it's easier to set them down or take with you.
[QUOTE=]What pattern did you use? [/QUOTE]
I used the "4 Stitches Per Inch" pattern in Getting Started Knitting Socks because it was for bulky yarn. I've made socks before so I pretty much just used it as a guide though.
