Firstly, thanks to all on this forum for your immaculate hammocking knowledge.
I ordered 10 yards of silnylon with intentions to build a blackcat, but this idea from Frawg piqued my interest.
Pseudo-Cat Tarp Experiment
I liked the fact that I could make 3 tarps instead of 1 with my amount of material, so I decided to give it a try, except I wanted to execute Barry's suggestion so that I could close the ends well.
I have not added the extra tie-outs for closing the ends yet, but the basic tarp shape pitches well.
It's 5'6" by 10'.
