I had thought of using a re-enforcement patch (and probably will) but it kind of defeats the idea of not sewing my ridgeline. When making this tarp, I followed the idea I saw elsewhere on this forum of not sewing the panels together at the ridgeline. Instead I made two flat felled seams on either side of a full width of fabric, using only half a width of another piece on either side. (Actually, this point should be far enought out to the side that a leak would not matter...)
BillyBob, those JRB clips are a very cool looking solution.
After posting this I also went out back and tried to do some trouble shooting and found that if I sit down further into the hammock instead of near the near edge, the angle is not as bad and doesn't stress the tarp nearly as much if at all.
Thank you all once again. This place and these people are great!
