Has anyone used a high quality blackout cloth for a d\r? I had some material that I purchased many years ago from Porters. It was great stuff, totally black, even with the brightest sunlight coming directly into a d\r window. Unofrtunately, my supply has run out and I need a replacement. Any reccomendations? Has anyone used this stuff:
If you use this stuff, do you secure it with hook and loop (velcro)? Is it light tight at this seal? I am finicky, so I want TOTAL blackness.
