Homemade Finding Nemo Diver costume. Black long underwear. Neon green fabric strips are fabric-glued to legs and arms. Diving cap is sewn from a ski-cap pattern. Tank is a painted soda bottle. At the hardware store I found the silver crank, and black tubing which I glued to the top of the tank. Black nylon strapping was sewn together to hold the tank and hang on the shoulders. The net is strung around a wire hangar, with the end cut short and stuck into a plastic golf club handle.
