I finally was able to transfer the images of a tarp to here...this is what I call the mooshi tarp, the smallest of my 3 cat cut tarps, named for the smallest of the 3 stray cats we took in. (the other two are the Bart and the Monkey, named for the remaining two cats; sounded better than the small medium and large! I'm actually not that much of a cat guy, oh well...) 1.1 oz sil, 210d spectra reinforcements from scraps I had, GG tie outs, not sure if I want to switch to d rings. The purple is a cool color to look up at but not stealth. I started to figure out the BB curve generator, but being a carpenter ended up grabbing a clear piece of pine 3/8 batten and flexing along the material until I liked the balance of curve and weather protection, then measured the height of the arc and used it on the corresponding other side. All three are different, just experiementing I guess. I did the three in three days, down to about 4 hours or a little better for one with a ridgeline, less for a one piece panel. The others are gray and black for sneakier trips. These were fun projects, quickly gratifying and they work very well, we had two at TD in the rain with no problems. I would like to fool around with beak style tarps though, and with midfield tie outs like I've always had on my regular camping tarps and try pitching it like a gambrel rood for lots of space around the hammock for ease of setting up bed, ventilation, etc. also wicked wind resistance with about 6 tie outs per side plus three on each end- that's alot of guy lines but it's held up to bad winter storms on the ground for me, and with a beak...I better quit typing and go sew!
