I am planning on building a diy screen. it will be 120 inch and looking to use spandex for AT screen. my room will be a home theater with total light control. projector will be an epson 3010. i was wondering if i should use a white spandex or a silver spandex for a dark room. also if anyone has any links for good spandex. i live near a joanns, but not sure what i should be looking for. i read in some threads of the spandexworld spandex. can i get similar at joanns or do i need to order. any help would be great. thanks.
