I noticed the black/white tent material you had on your web page and I was
looking for a 76″x42″ strip of material that would block 100% of vis and UV
light for a dark room. Is this something you might be able to help with?
Although our black/white blocks 100% of light I am not sure if it would be suitable for dark room use. There may be an occasional pin hole. Perhaps you could block any pin hole leaks with back tape of a dab of paint..
