I made these little guys as small gifts for friends. I used sheet felt and buttons. The green monster has a pocket in the back. Actually the green monster is called Monster McGiver, because I filled him with "survival" items. He has a pencil, matchbook, safety pin, measuring tape, Advil, nail clipper and room for emergency quarters. Monster McGiver is a little bit too big to be a key chain, so I'm planning to give him to someone who has a locker... he can be a locker buddy.
