Isn't it fun?? Best luck I've had is to roll it back the opposite way, but obviously not as tight! It'll take practice! Maybe 2-3 times! Put on gloves!
When stapling, do one verticle side fully, first, and then the horizontal sides, alternating top and bottom, while pulling taut - should come out perfect! Convex side towards you!
Another tip - don't even try to measure the screen - count the open squares, twice, and mark with a marker, and cut as close as you can to your verticle edge, so you've no sharp ends!
[I've only cut about 1000 ft. of it]
