They're finished! After much ripping out of the ribbing because I kept forgetting which round I was on, I finally got the second toe done last night, and M.M. is wearing them as we speak. The photos I took didn't come out very crisp, so you can't see the detail too well, but trust me, I'm quite pleased with myself.
I've already cast on for yet another pair of socks, for my brother's Christmas present. These are in worsted weight yarn (Cascade 220, a heathered blue color) on size 3 needles, and it all feels huge compared with the teeny tiny gauges I've been working with for the past 3 projects.
