I made the leg 7 inches instead of 8, because I was starting to become concerned that I might not have enough yarn for 2 socks otherwise. I’m probably just being paranoid, but we’ll see. I’m horrible at judging volume. (Later note - I was just paranoid. I have plenty of yarn leftover. Oh, and as for the length of time it took me to finish them - that was just because I have a tendency to suffer from second sock syndrome).
