I,ve been bitten badly by the MYOG bug. Yes I've been stung a few times by my own flawed designs or poorly executed projects. But this is a happier story of lessons learned from mistakes of the past.
Recently I constructed a full length bug net to use under my tarp with a tyvek ground sheet. When I did a trial run in my back yard I realized that I needed something roomier and much easier to use and set up. This thread shows the results of my efforts and the solutions to the difficulties encountered with the bug net/ground sheet combo.
In the pictures below you see inside of the bivy my Ridgerest short pad, homemade quilt, inflatable pillow with MYOG pillowcase.

This 8.45 oz setup actually added weight to my pack. The bivy is .75 oz heavier than my hard to manage bug net and ground sheet combination. :-)

I got all of my materials for this project from Quest Outfitters. My feet are now covered by a 2.89oz / yard lightweight waterproof breathable top layer and I have a roomy no seeum bug net that is supported from the ridgeline of my tarp.

I can open the net using the dual 2.5 mm zippers and leave it hanging if I have to get up during the night.

I can also roll up and stow the bug net using the attached lacings if the bugs don't happen to be a problem and all I need is a "ground sheet".

The tapered foot box area is very roomy. It is 11.5" high and 24" at its widest point. The bottom is 29 3/4" wide and the arc'd top is 41 1/4". This gives me a girth of 35 1/2" at the shoulders or a circumference of 71". I believe this is plenty of room for a back or side sleeper to be comfortable.

The bivy has four of these stakeout loops to help keep it from sliding around like my tyvek goundsheet. The 1.1 oz silnylon bottom of the bivy is now my groundsheet.
My bivy, sleeping pad, inflatable pillow and pillow case, quilt and 2 stuff sacks, tarp and pack weigh a total of 52.7 ozs. That is 3.29 pounds total for the big three. :-)
I now believe I am protected from the creepy crawlies, the flying insects and no seeums. This project cost @ $50.00 in materials and took about 15 hours of my time to complete. A lot of time was spent transferring measurements and cutting out full size patterns.
There are some challenging seams in the footbox area and where the zippers end on the sides of the bag. But I am happy overall with the outcome and I am by no means a sewing professional.
Party On ! 2010
