My DH needs smaller feets

I found some worsted merino from Handpaintedyarn.com in my stash and started a pair of socks for DH. I'm doing them toe up because I'm not sure that I'll have enough yarn to do two socks if go from the cuff down. I weighed the ball of yarn and it's about 3oz, so I figure I'll stop the 1st sock at 1.5 oz. That should leave me enough to do the second sock. Unfortunatley DH has some monster feet so he'll probably end up with a pair of anklets, poor guy.
