I own two nylon 9x9 tarps already, but I love playing around so I decided to try a clear plastic tarp
Duck Tape Brand White Duct Tape
4mil Clear Plastic Sheeting ( 10x25 roll )
3/8" reflective cord
I simply cut a 10X10 square from the 10X25 roll. I then fashioned tie outs from the duct tape, and loops of the 3/8" cord.
I have it hanging in the backyard test lab.
This version is a testbed. I am testing the tie-out system, and also seeing how robust the 4mil plastic is without any reinforcement. Durability of the plastic is also something I am curious about.
If things go well I plan on taking the concept to a 12X10 tarp that I can close up with doors
