I bought Blackout Cloth from Carl's Place and I investigated it before I started stapling. Unfortunately my eyes must have missed it until I started stretching the cloth. I shouldn't even call it a rip. From 3 feet away it looks like the smallest spec of dirt. From 6 feet away I can't see it. But I'm wondering for you "DIY" folks, could I dab some sort of microscopic whitish liquid on this bad boy and be ok? It did not go through on to the cotton side. Just the polyester. I feel bad for even complaining. I know if my wife saw this she would say, "Really? You're concerned about that? I can't even see it!"
But I want this to be done once, and done right. Anyone?
