Has anyone come up with a very light method of tensioning their tarp that you would like to share?
I'd qualify more as a cheapskate than a gram weenie, but here are a couple things I've tried.
Scünci hair ties with mason line are light, though weak:
You can also do this with cross sections of bicycle inner tube, Also works with the plumber's O-rings that fin came up with. Both tend to be stiff, with limited stretch, and tend to recover somewhat slowly once stretched.
In this pic you can see cross sections of bicycle inner tube, cut on the diagonal for greater length:
Cheap, easy tarp tensioner. Looks like Fin has yet another great idea. I've already purchased the parts. Now I just need to put it together.
The road goes ever on and on Down from the door where it began. Now far ahead the Road has gone, And I must follow, if I can, Pursuing it with weary feet, Until it joins some larger way, Where many paths and errands meet. And whither then? I cannot say.
