I am in the middle of building this plane and have begun to think ahead to the task of covering the wings. The bottom of the airfoil has a concave or bow shape to it. My first question is, what fabric do I use? My second question is, how do I keep the covering from pulling away from the bottom of the wing when I shrink it? If not done right, the wings will essentially have a flat bottomed airfoil.

Any advice will be greatly appreciated.
