JZ,

First, go to the craft store and buy some irridescent plastic wrapping. It comes on a card, is about 5 inches wide, and looks like a pearlized embossed ('crinkly'?) sheeting. It's not expensive.

Buy some of the sticky back foam in colors of your choice.

Stick the plastic wrapping stuff onto the foam.

You get irridescent or 'pearlized' colors with this. Works great for Crease Flies.

I'm partial to the white foam, as it allows you to color it easily with markers or an airbrush, but the black and dark green look awesome as well.

After you put on the coat of epoxy, the thing looks 'real'.

Good Luck!
