canopy netting

I put in the roll on bedliner for my trailer. I used pray can DIY bedliner for the lumber rack and Herculiner for the trailer bed. Now I want to make a canopy. I think I want to use the military heavy camo netting. I can run it off the lumber rack out to some stakes. It wouldn't be water proof but it would provide shade and cuts down on wind. Any other ideas or suggestions on a cheap netting source would be appreciated. 

Try to avoid used Army NATO Camouflage.  There is a ton of it out there and most of it is junk.  The stuff becomes sun dried, mildewed, and has ten thousand rips and repairs in it.  I know, I have repaired a butt load of it and the stuff is always falling apart, catches on every button on you.  I highly recommend trying to use a couple of old camouflage rain ponchos, they offer some rain protection, roll up easier, don't hang on things like netting does.  Can be thrown in a washing machine, and can be repaired with grommets if the snaps fail.
