Not really to specs
I purchased a 20x20 tarp framed up for my workspace. When I installed the tarp, it ended up having more of a oblong shape - I was able to line up 3 of the sides, but the 4th had significant overhang of varying degrees along the edge. My previous 20x20 tarp (which blew down in a storm) was perfectly square with my framing. Additionally, because I'm in Hawaii, shipping it back for a replacement would have been prohibitively slow/expensive.
