advantages to square vs. rectangular tarp?
I've got to get some tarps for my fiance and myself. Since we're going for cheap, we'll be starting out with some "ye olde blue tarps" from WalMart. I think they were $7.99 last I looked at them. Definitely not what we'll be wanting for the long run, but cheap and quick until we can afford better.
They have a 9'x9' and a 10'x8' version (plus different sizes, but we don't want any bigger). Would there be any advantages to a square vs a rectangular tarp? Hung diagonally, their ridgelines are about the same (approx. 0.1 foot difference between the two).
