Each time I purchase outdoor fabrics, I always get more than I need, so there is always fabric left over. I make stuff sacks out of that, and the game is to try to make a stuff sack that is different from any other I've made. They vary by size, shape, color, drawcord type, and drawcord toggle type. I give most of them away to my hiking friends and keep a few.
Silnylon is awfully slippery and hard to deal with. Coated nylon is good. Pertex is good. No-see-um netting is good since you can see the contents of the bag. "Wedding mesh" is terrible.
