The price of socks

If these were my socks, I'd be doing the heel right about now.  They're not my socks, and I have a way to go yet.

Mountain Colors Bearfoot is interesting stuff.  It shines.  Also there's an alarming tendency for stitches to jump off the needles and burrow down two rows before I know what they're up to.  It's also soft and warm, with a halo of mohair around the finished fabric.  The socks are for Hubby, his first hand-knit socks.

Got chatting to a couple of Knitting Guild ladies on a stall in the Loop.  We talked patterns and yarns for a bit, then got onto pricing for the socks they had for sale.  Given that the yarn usually runs at $12 or more for each pair of socks, and it takes a while to make them, what's a good price?  I loved the Harlot's idea of calculating the number of stitches and putting it on a tag with the socks ("please wash these twenty thousand hand-made stitches in warm water and do not tumble dry").  Fastest I've ever made took six days each sock, that's two weeks of work for a pair.  So what's reasonable to charge?

(No, I have no intention of selling Hubby's socks to the highest bidder, I'm just curious.)
