Profs to old adages. I.e, "Less is More", "Keep It Simple Stupid", and my personal favorite - "Intelligence is genetic, wisdom is purchased with blood, sweat, and failure."
After deliberating for an inordinate length of time over tarp tie outs, I determined that a single piece of grosgrain along the ridge line, formed into loops on either end would offer the most strength. It also seemed logical that trimming the edges with a single piece, with loops in the corners, would similarly offer the most strength. After untold hours of positioning, pinning, and injecting thread, my hexcat tarp was complete. It looked beautiful. I was very happy with it. Barely able to contain my excitement, I ran to my yard to string it. It was then that I realized the error in my logic. The grosgrain did indeed make the tarp stronger. It also prevented it from achieving any degree of tautness. Rather akin to putting a loose piece of canvas in a frame.
So, another order placed to RBTR. Another chance to aquire wisdom.
