If you use big checks (say 3" or so) checkerboard is really pretty easy. (I like big checks because you can see them in the sky.) I just cover the wing with the lighter color. Then I cut out the squares of the dark color (a cutting mat with lines on it really helps). The easiest way to get them on permanently is trim solvent. With a little practice, you can hold one half of a square down with your fingers to maintain the position, lift the other half, apply trim solvent to the wing, and smooth the other half onto the wing. Then you lift the free half, apply trim solvent to the wing and smooth down that half. It sounds like it would take three hands, but it can be done, and with a little practice, no bubbles.
