Those were socks that men used to wear. That pattern was free in each package of socks, they came in both colors, blue and brown socks. I made monkeys for most of the nieces and nephews when they were babies. Last year at Christmas JC Penny had little 6" ones with kids names on for Christmas ornaments. Not long ago they still had leftovers for $1. each, they were in the area of the bath towels.
