I have that book too!! They are quite addictive. I've made quite a few and I'm always buying socks yet never have any to put on my feet. I've made sock monkeys for years...so this was a fun change. I don't have any pictures right now....but I'm about to make a bunch more for a charity craft sale at the hospital I work in.
My cat even has her own that I made from one sock and left featureless. (No buttons to come off and be swallowed.)
