I was wondering if I use Ripstop Sil-Nylon to make a sock that would eliminate the need for a tarp. My idea is to sew two pieces of fabric (59"x3.5 yards) into a tube, with velcro on the seam facing the bottom as the entry. Each end would be a sewed channel (sorry if this doesn't make sense) that could be able to cinch tight with paracord running through it and a cord lock. There would be a ridge line either inside of it or it would hang from one outside. The sides of it may have tie out points to spread it out if I feel they need it.
I have the material to do this, and if experienced hangers feel this is plausible, then I'll start the work on it. If its not, I'll make a larger tarp.
Also, sorry if I didn't explain this well. Please tell me if there's a vague part, and I'll try to elaborate on it.
