I finished these baby socks for a friend (had started them here in september). The baby shower was on Saturday, and baby is due mid-January. I used a leftover yarn that I can't remember the name of, but I'm pretty sure it's cotton. These will be perfect for spring/summer. It's probably hard to tell, but the foot is about 4.5" long.
If you have a Ravelry account, you can see my project page here. Otherwise, the details are that I used the On Your Toes sock pattern by Ann Budd, from the Summer 2007 IK magazine. Unknown yarn, size 1 bamboo needles, 40st count for foot and calf. Very fast socks, and I'm happy with the pattern, except for the sewn bind off at the top. Any other sock-knitters have a better method?
