For my Super 8 I have a projector screen I can hang up in the roof. It is too small, though for my 16mm Elmo 16CL. For this I have used a white sheet, that is; I did until yesterday. Now I finally got a projector screen mounted to the roof at my cabin (where all my film stuff is). The size is perfect for my 16mm. Got it for free from the school where my mother in law works. They are about to replace all of this old equipment as they are building a new school with more modern solutions. I guess I should build some wooden casing around it as it would get a higher WAF (Wife acceptancy factor).
