Insect Netting for Camper Shell

Does anyone have ideas for how to best install insect netting across the back end of a shell with the rear window open? I'm trying to figure out way to get good ventilation for sleeping in the shell on warm nights.

The DAC tents seem like they are a bit too much, the way they wrap around the sides and top of the shell, even to the point of blocking ventilation on the side windows.

I;m thinking of perhaps cutting insect netting to size and sewing velco on it? Other ideas?

 

I'm lazy, I just drape one of those large mosquito cot nets over the back and put some weight on it (a long bungy would work as well). Works fine and I think I paid like $10 for my mil surplus model.
