Of course, it's going to be in the mid-70s locally this week, now that I have finished my friend's wool socks. But we can depend on winter to return. And, assuming that he likes them (which he won't, if he wears them when it's in the 70s!), I now have the numbers to make him socks-that-fit as often as he likes.
Pattern: mine, toe-up, with several fittings along the way to ensure a good fit (toe width, foot length, heel, leg height)
Yarn: Regia Allround Color (discontinued), taking some care to start both socks at the same point in the color changes so that they would match
