I used safety eyes for his eyes. I sewed him a little mouth by pulling yarn through the back and around the front where I wanted it to be and then putting the yarn back inside. I just tied it in a knot and called it good. The little bones are iron on transfers and I just glued them on. For his hair I drew the outline of where I wanted his hair to be and then I just kind of filled it in with yarn. It's kind of hard to explain how I did it.
I came up with my own pattern for his hoodie and then I sewed his arms on outside of it to secure it on his body. His little hood even comes off.
That's about it! I'm really happy with the way he came out. I think it's super cute and he's going to look totally awesome on my bookcase.
