Wanted to do an awesome homemade Little Green Plastic Army Man costume of these for years. I made the bazooka from plumbing parts, the walkie-talkie is from a Barbie refrigerator and plumbing parts, the rifle and grenades were toys painted to match. The stand is a routed piece of wood painted to match.
This was a labor of love. The trick was to get everything to be shiny. The uniform was coated with 2-3 layers of modpodge. This allowed the paint to shine and sit on in the material. The face was a cheapy transparent mask painted to match.
Really was happy with everything on it.
