Though I am sure might be known already. here is a very simple idea I use for my cover install/removal to make it easier to know front/back
With the cover on the car, I fold it in thirds lengthwise along the car. I then roll the back up to the windshield wiper area and then the front to the windshield wiper area. That makes the rolls different sizes and easy to see front/back when reinstalling, just placing in front of the windshield.
I know its very elementary but thought I would share anyway.
