Luckily I found a two pack of socks on sale at Wal-Mart and they worked great just a little skinny....that's why we decided to make them ballerina monkeys with tutus and bows.
They are quite lanky
And I'm gonna have make another one for my little boy who has fallen in love with these, I think I will go the more traditional route with his.
If you would like to make your own this is the tutorial I used, it was very simple and easy to follow.
