Robert, thanks for the tip on Porter's. I think I had seen that before somewhere. It sure isn't cheap at $13/yd. What I'd really like to try is to make a 'popup' type tent made out of the stuff. Wouldn't it be cool if you could take one of these and use darkcloth instead of netting? Talk about portable!

Well, I know it can be done, but $13/yd would make it quite expensive....
There are also the ez up type canopies out there. Again, that's a lot of fabric.
