I have what is probably a pretty dumb question about fiberglassing balsa sheeted foam surfaces. So here goes:

I have read nearly all the threads on glassing, but something still puzzles me. How to apply the cloth around squared wingtips or any other areas with a sharp corner?

I've seen where most folks can cover their wings with one piece of cloth top and bottom. I assume that they have wingtips that are rounded. Also, what about "cutouts" for ailerons? I was guessing that this area would be a seperate piece and done first, then do the top and bottom surface.

I'm really looking forward to my first glassing project, but I'm still a little timid. Maybe the 'ol pros can lend a hand here.
