I used the Simple Sock pattern from Cat Bordhi's book, "Socks Soar on Two Circular Needles". I used Zitron Trekking XXL yarn for it, and knit it on two circular size 3 bamboo needles from Clover.
My only regret is not buying the Addi Natura needles; the joins on the Clovers leave a little to be desired.
Here is Picture 1:
Another picture off the foot:
And, of course it's out of order, but this is a picture of the sock in progress last week. I zoomed down the foot because it's a chunk of "mindless knitting" and then did the toe decreases yesterday and today on the ferry. I came home with only the Kitchener stitch grafting across the toe to do. I looked it up in one of Debbie Stoller's "Stitch 'N Bitch" knitting books (I have both knitting books and the crochet one, too), and though I didn't really understand what I was doing, I followed her directions and it came out great!
I also love that Trekking XXL really gives you a TON of yarn for the money, and it knits up very well; no weird split stitches like some yarns.
