Great socks. Your son is lucky to be loved that much! I'm so glad you had a good time and next year, again! My son has big feet too (someone said they run in our family) and I've yet to undertake knitting socks for him. I've intended to make him some and your accomplishment might be just enough inspiration to bump them up on my to knit list.
Happiness is catching that dropped stitch while it's still fixable..
