order from OWFINC.com
If you buy 20 yds of one type of fabric you get your entire order wholesale. I normally do it with ripstop. 10 yds for a couple quilts, 5yds for a tarp, a few more yds for some packs. The cool thing is it doesn't all have to be the same fabric. I was told any ripstop (or any mesh...) would qualify, so i can mix 1.1sil, 1.1uncoated, 1.9 coated, 4oz coated to make up my 20 yds. They sell everything else you need too.
Webbing-gross grain 1/2" or 3/4"
thread- Gutermann - Don't need anything bigger than that but can use size 46, don't go bigger
I have used the yellow 1/16" drawcord from them for guys, it works pretty good, there is better stuff out there but it is cheap and comes from the same place.
nano-see-um would work fine, but at a big price bump.
I think the net tent is way over built anyway. Do what ray does now, throw some mesh over your head (attached to quilt near chest)
