This is the first pair of regular old sock-yarn socks I've knit for DH. He does have two other pair, in slightly thicker yarn, that he claimed to love but never wore. A while back, this yarn demanded to be knit, and spent a good month refusing to tell me who I was knitting for. Turns out they are DH's, and he likes them well.
I used a rather funky combination of a short-row heel and a Cat Bordhi heel and a flap... sort of... It seemed to work okay, but I'm still iffy on whether I'll do it again.
They're knit from Elann's Harlequin sock yarn (acquired during an "unloved sock yarn" swap.)
