Couple of other tricks.
You can actually cover on the canopy itself. It is a little tricky because excess heat will deform the canopy but it can be done. With this method the inside of the canopy is the same color as your covering.
Another trick which is also difficult is to mark the inside of the canopy to the point you will paint or cover. This enables you see where the covering/paint will be seen from inside the canopy. So you don't see a primer or glue from the covering you paint that inside portion black with some Lexan spray cans. Where it gets tricky is that now you have to match that inside black with your outside colors so there is no over or underlap.
I did this on my 35% Edge I built.
