Ive done this to my spinn tarp and now to my cuben camo winter castle...aka my baby :-( now has a hole from swinging out spreader bars on my BMBH. As I was getting in my hammock I sat too far on edge rather centered, which I know better and pop goes the hole! Since apparently I'm not competent to pitch my tarp properly I made these after I patched my tarp. These should do the trick...along with getting my head out of my arse!
