1 square box (harder to find than it sounds)
54 colored felt squares (2 larger where arms come out)
1 can spray glue
2 rolls black electrical tape
First, cut an area out of the box for your head and arms.
Cut the felt squares so you have enough room for 9 colored squares for each side (3 X 3)
Spray one side of the box at a time with spray glue and apply the felt squares
Use slightly larger felt where the arms come out to cover the hole.
Apply black electrical tape to cover the seams and edges... Be sure not to stretch the tape too much or it will try to peel off when it's cold.
