I keep having this insane desire to cackle like the Count from Sesame Street, and count, 'One, one pair of red socks! Two, two Christmas gifts complete!' Probably I'm still really underslept.
As I was knitting up to the ankle, I was noticing that the relatively plain fabric had almost no give to it. So I increased a few stitches at the bottom of the foot, and included those with the heel stitches when I worked the short-row heel. Result, the socks do not stretch or pull at the point where the last heel stitches rejoin the leg. I'll have to remember that trick.
And the slight pattern up the side gave me something other than rows to count for length matching purposes (I hate counting rows), and provides a bit of decoration to relieve the plainness. Not that plainness is a big issue, since these socks are destined to disappear into boots, never to be seen again, but you get the drift.
And now, to knit something that's not red!
