I made the Nightwing Tarp Tent references in the first post of this thread:
A couple of deviations from the plans:
1. Made it 1 foot longer
2. Added extra tie out at mid point of each side
3. Designed if for use with site found 'tent poles' (ie sticks/branches found on site)
As shown, only 6 stakes are required ( 4 corners + anchor for front and rear guy tie outs)
If I made another one, I would probably double the width of the netting around the perimeter of the bottom.
Not sure of the exact weight, but is about 1/2 the weight of the single person, 3 season tent with poles that I normally use.
Packed size is about 5" diam x 10 or 12", including tent, tyvek ground sheet and stakes.
