I keep looking for something that will suffice for firefly wings that would look like these http://www.mattbezak.com/images/animalia/Firefly_Pin_lg.jpg (like, a mold for them) and am drawing a blank everywhere I look. Am I looking in the wrong place? does anyone have a better idea?]

If nothing pans out, could you not cut them from gelatin sheets? Just an idea!

This might help you.
