advantages to square vs. rectangular tarp?

I think you mean "rotated 45 degrees". If you rotate 90 degrees it's still a square.

HA! Yeah, sorry 'bout that...

I think in this case "square" is rotated 90 deg, think diamond

OK, that makes sense. The old diamond approach.

Search "hammock" or "tarp" in the picture gallery and you can see the difference between a rectangular tarp and a square tarp deployed like a diamond.
