When making my cat tarp. I did not cat cut the ridge line. I did cat cut and double cat cut the edges. I am not sure if i am totaly positive on this, but it makes it pitch taught A frame style, or as a flat lean too pitch. This was my philosophy, and it seams to work well either way. I tacked my fabric to the wall and maked the cat cut with a sharpie. I did this with a piece of cord tacked as wall with the correct sag? Not rocket science, but it works? Excuse, my grammer, I have had a few after a very hot day at work! Good Luck
