The house I'm living in now has enough space for me to upgrade to a larger screen. Currently I have a 84" wide pull-down screen. I want to build my own screen at 105" x 45". I would like to build a wooden frame and cover it with matte-white screen material. I would need material cut-to-size at about 110" x 50" Surfing the Internet I've found the cheapest I would be able to get it is about $200. Surely there is somewhere I can get it for less that $100? Does anyone know where I can get cheap material, or maybe even something that isn't meant for screens but would work just as well?
