Go down to the local pharmacy and buy some Kling:

This stuff is perfect for netting. After you get a roll, buy some fabric dye, I use Rit, and dye the whole roll of bandage. You can't tell from the photo, but each roll is doubled, so if it is a 2 inch roll, in opens up to 4 inches. You will have enough netting to make as many camo nets as you want. If you need burlap in netting, just weave facial tissue through the netting.
