Another single sock slowly grows

This was last week. Cute colors, like rainbow sherbet.

And now, about 4 1/2 inches along. I'm going for a 5" k2p2 cuff.

I made a discovery about my sock knitting. I thought these socks were being knitted on size 2 needles. Nope. They are 0's. All my double points are actually two sizes smaller than I thought. No wonder all my socks are firm and dense.
