Anyway. I made these socks for Jeff. They're based on "Toe-up socks with a difference" by Wendy D. Johnson, but made in worsted weight yarn, and are obviously larger since man-feet tend to be more demanding size-wise.
Did I do the math? Not at all. I made a half-assed guess based on what my gauge usually is, and winged it from there. They fit, so either I'm a freaking genius, or I'm very, very lucky.
Yarn: Cary's BFL in Cameron, by Three Irish Girls.
