Grizz, for the netting I used a 41-48" wide piece of material, 41" normal and 48" when it's stretched if you know what I mean. I just used a rectangular piece that was sewed to the sides, but at the top and bottom I did what I think is called "pleats", where you take the fabric and fold it on itself and sew, which enables you to sew a 41" piece of material on say the 24" draft stopper at the foot end.
The foot end looks rather ragged as I had to sew extra material on to lengthen it because cutting the hourglass shape made the overall length of netting needed longer. Also cutting it changed the forces on the fabric somehow and things pulled apart that didn't before, so I just cut netting and sewed it in places that needed it. lol. Like I said, the foot end looks ragged, but it'll keep the bugs out and "nevermind the man behind the curtain" and everything will be good to go.
On the whole though, most of it is rather taunt and stays out of my face and feet. I was thinking I would need a ridge line to help, but it's doing pretty well so far. I do have a little bit extra netting that makes a nice shelf on the side if I wanted to use it like that, but I plan on putting a ridge line with bags/hooks on the inside....I think, I don't know, well see.
