For supplies I used 1/2 inch foam, felt (better to use fleece) , ping pong balls, black yarn, spray adhesive and TONS of hot glue.
For his shirt I recycled one of mine and cut it up to make a small one. For the arm rods, they're recycled metal coat hangers.
I'll post an how to instructable in the future as I practice and get better. If you have any tips please leave them in the comment box. Thanks
