That's a great looking sock. Maybe after you wash it, it will shrink just a tad.
I know what you mean about not wanting to do the same thing all over again. I'm always surprised that the cardis I've made end up with two sleeves.
Maybe you could learn a different technique for the second sock (color knitting, maybe?) 'cause who says both socks have to match? Not me!!
I've always said: Just because you buy (or make) matching pairs of socks, that doesn't mean you have to wear both of them at the same time!
