Don't know if anyone's tried this but it seems to work quite well.. especially if you do the table edge wing curve thing...
Once you get the curve you want take a few foam strips and get a similar curve. While maintaining the curve, glue the strips in place. Once the glue dries the curve remains nice & stiff.. This particular wing is a full 20 x 30 foam board.. half of a dihedral wing for a creeper I'm building.. It's just a personal preference.. I don't like ribs.. and it looks neater. sweeter, and more completer..
