Please look at the pictures. All imperfections on the pictures. Please see how it is wobbly in the center i am not sure if it is normal. When i put 4 weight on the corners it is still a bit wobbly in the middle part . It is not laying out flat like a piece of paper. Also please look at the last picture i circled the spot what looks to me like exposure to moisture or water. It is not visible on the front. Maybe that is why it is not sitting flat when i try to stretch it. I am sure if You frame if it will be ok.
