I have an Outdoor Products Polyurethane Coated 12' x 9.5' Nylon Tarp that I got from REI during their annual New Years Sale. It was 30% off, and I used some of my Store Credit to get it for less than half price.

I tied some 550 Paracord to the grommets and use those for stakes and lines rather than the grommets.

Here's a similar Tarp Setup to what I put up except I use a centerline tied to a tree if at all possible. If the link doesn't work go to www.youtube.com and search for "Etowah 8x10 Tarp Setup".

I plan on adding a mosquito net to this setup.
