One pair of size 15 (he says 14.5) york socks made with single ply merino wool. I didn't spin it myself as all the stuff that I had previously spun is much finer weight, but I'm totally hooked on Naalbinding. Tomorrow I'm going to buy the wool to make me some mittens. I made some slight modifications to the pattern (read huge) so that it would work on the wearer. I also made the top of the socks extend a little higher so that they work better under his shoes.
