I adore these silly Monkeys. My kids went nuts over them. I used this tutorial which I think laid it out in a very simple way.
The only thing is I can never find the sock packs at walmart, but Target has a HUGE supply of them in the women's section for $2.50 a piece. The are knee high length, but just cut accordingly and they will turn out so fun.
I have to admit my free hand stitching stinks, but in a way I think that is what makes them cute--is that they are not perfect.
