I am going to sew a sock bug net, but I'm not sure of the material to use. I got a 'rectangular mosquito net' made by coghlan's, and was thinking about cutting it up for the sock, but I'm not sure about the hole size. Looks fine for keeping mosqitos out, but not sure about the smaller creepy crawlers. Anyone have advice as to the best/lightest/cheapest bug fabric to use? I can't order anything, don't have the time, so it would have to be from a wal mart or joanne fabric type store.
