I don't think I have enough yarn in the two skeins I bought to make a whole pair of men's socks! I started at the top and knitted 7" of 2x2 rib, and then started the heel flap. Now I'm about 3" into the foot, having turned the heel, and I'm running out of yarn on the first skein!
This is why I prefer toe-up!
Plus I don't expect to finish these by Adam's bday, which is 10/8...
And another thing: I have to complain about sock patterns. Whereas in patterns for other garments you get a variety of sizes, for sock patterns you usually only get one size (Ladies' M). It's not right.
