I just wanted to share (i.e. boast about) my most recent MYOG success - a minimalist bug shelter for SUL travel. I have the Gossamer Gear bug net that drapes over your sleeping bag and hangs from the ridgeline of your shelter, but I felt it was clumsy to use and didn't provide 100% protection from things crawling on the ground.
What I settled on is a basically a net tube that extends half the length of your sleeping bag or quilt and closes on a drawstring around hip level. The top of the net has a couple loops to allow hanging, and the two corners at floor level at the head of the sleeping bag have loops so that they can be staked down if necessary.
Total weight is 53 grams (1.87 oz) including string for hanging. This compares to 70 grams (2.47 oz) for the GG bug net in the same set-up.
Other advantages are that this net can be used just as easily in a hammock (unlike the GG net) and that it can be used as a headnet when walking, saving another 30 grams (1 oz) on a separate headnet. And headnets you can buy in stores are of regular mosquito netting, not no-see-um mesh like this.
Here's a picture. You can't tell here, but the net has been pulled upward, allowing maybe 8-12 inches of room above one's face.
I'm curious if anyone else has experimented with minimalist bug shelters in a similar way.
