What's a couple more WIPs?

I also started knitting these socks. This was the first time I tried the Figure-Eight cast on. I used these directions. I had to start over a few times, but once I got it figured out, it went pretty well. I'd like to make these socks tall enough to use up all of this yarn, but I want them to match and I don't want to run out on the second sock. So maybe I'll knit them both at the same time, but then I'll have six strands going and the potential for tangling seems pretty high.
