After a month and a half of staring at boring boring grey, I finally finished GF's socks. I'm very pleased with the end result. More importantly, he's very pleased with his socks. And they make his feet look surprisingly normal.
Of course, after I finished the socks, the temperature soared for about a week here, and GF couldn't wear his new pretty socks. Instead, they sat on the table next to the couch. Eventually the temperature ebbed, and he got to wear them to work this past week. He loves them, naturally, and now would like more.
Lesson learned - don't introduce new addictions you aren't prepared to feed.
