OK the piece is 24' by 60'. I need the width, and the stains are directly in the middle, so cutting the stains out is not an option.
I never actually checked the back, but I will!
The fabric is in decent shape, I feel like it could hold up to a bleaching. I might try that first (I am going to be lighting it so as long as the bleached fabric looks close to the light blue, it should work?)
If I decide to paint it white, where can I get flameproofing material?
