You might not need to cut. They sell it in so many sizes there it a chance they have what you want in stock. I just bought 2 more, 16' long and 6' wide. They are nearly perfect for covering cubes built on 4 pallets. Remember you lose 6" or so for the hems.
Thanks Paul Bunion! I ordered an 8'x30' and plan on cutting it the width I need and wrapping in a 1"x2" (or whatever is on hand), then screwing it down to the stack to secure it. I gave up on my grommet idea after Stinny posted this method. Much easier!! They sure do have plenty of sizes. I've got them saved to my favorites for the future!!
It's here! The tarp is very tough. It's thicker and more pliable than I hoped for. Thanks FHC!! I hope it holds up well. Another batch of storms on the way or I'd be putting it to use!!
