Monkey Hut

As in the real world plumb and square are good things, however the material and nature don't allow for it most of the time. That is why I like the flexibility of my style.
My technique for lay out is to measure my width 10.5'. take my tarp fold it so it is 10.5 wide, this give me two good squared edges. then I put rebar every 4 feet along each side, and the last one about 4" beyond the length of the tarp. I use rubber strips to strap my ribs to the backbone. Then strap the ends to a candy cane in the ground. Bungee the tarp on open your chair and crackabrew!
