Ok, I know nothing about that stuff! I'd like to have a friend (who knows what she's doing) make stuff sacks for our tarps. The ones that came with them are so small, they must have used a vacuum sealer to put the tarps in them at the factory!

What fabric would you recommend for something that will be somewhat waterproof (so a wet tarp won't make everything else it touches wet as well), yet not super heavy and easy to work with?

Thanks in advance.
