Sometimes, being a compulsive makes life much easier.
See, I have this ball of grey yarn that I bought at Pennsic because, for some reason, having three different knitting projects with me was not enough. Perhaps it was the fact that everything at War has that little glint of "can't get it any other time"; whatever the reason, I have the yarn, and I'm making socks of it.
But I'm also using 2mm needles, which is slightly smaller than I usually use, and I'm not sure how much of a cuff I can do on each sock without running out of yarn before the other reaches a similar length. But being me, I have more than one set of 2mm needles, and also I count rows even when I'm not in fear of running out of yarn--I want my socks to be as identical as possible1.
So what I have now is two socks, each attached to one end of the ball. My plan is to do 5 rounds of ribbing per sock till I'm almost out of yarn. The really big bonus is that I have enough needles that I can have them both in progress at once; I don't have to keep binding off or switching to stitch holders or whatever (and if I did, I'd come up with some other solution, I assure you; even I'm not that much of a compulsive).
I must say I really hate this yarn; haven't a clue why I decided I needed to buy it. It's very very scratchy. Luckily Liam's tolerance for such things is far higher than mine, even on his feet.
1: I didn't do this the first few times I made him socks, with one pair that is particularly amusing because of it, using a self-striping yarn with blocks of four different bright colors between a darker background. Because I started halfway around the color cycle on the second sock, and because of the way the straps of one of his pairs of sandals falls, when he wears the socks with this particular pair of shoes it looks like one foot's striped with sky blue and green while the other's red and orange. The socks are clearly related because the background of navy blue is the same, but they look like fraternal rather than identical twins.
