I finished the sea socks. (Please ignore my super-white legs.)
Yarn: Society Socks, colorway #218, "Caribbean."
Pattern: Merino Lace Socks from Favorite Socks. I shortened the heel flap and picked up fewer stitches for the gussets, but I think they might still be a little big for my mom. Oh well, she'll like them anyway.
It's really hard to take pictures of your own feet!
