Garry, the same holds true for anything if you have a pattern to go by. Rather then try to "shoot in the dark" so to speak, if there's no pattern to go by, make one.

Sure it might take 30minutes or so, give or take, but end result will surely be worth it. The film covering is not cheap(yeah, I know, $10 or $12 a roll) when you consider 2 to 3 rolls per plane though, that can be almost $40 for a covering job....so you want the most out of it.

Start with a simple piece of paper or cardboard and just start drawing or trimming, get it close as you can. It will still beat trying to do it with much more expensive film. Paper is cheap, and you can restart/redo it and it won't cost a thing. For applications like the one above it will work. Have fun and I hope everyone's plane comes out good.
