Cellophane as a wing covering
I've used the "Gift Basket Cellophane" and shrink wrap for covering with great results. It's very strong, cheap, lightweight, and comes in lots of colors. I've used weldwood ( both types ) contact cement, to adhear it to the frame. The water based stuff, you can use inside the house, as it doesn't smell too bad. The heat shrink stuff, shrinks more than any other film I've ever used. USE HEAT SPARRINGLY! I wrapped an AL can in several layers and heated it with a heat gun, and it easily crushed the can.
