Hi, sorry if this sounds ludicrous, but is it possible to make a projector screen out of a bunch of neatly-taped-together pieces of A4?! My dad has a projector downstairs but the screen that it projects on to is fastened firmly (no chance of moving ) onto the wall. Rather than go and buy one just for a weekend I was thinking of simply lining up some A4 paper, sticking it together from behind and then layering it up a couple of times so that you couldn't see through it. Thoughts? Am I a loon for contemplating it? I'm not interested that much in the picture quality, only that it serves as a better projector screen than the orange hideous wallpaper that asphyxiates the walls of my room. Thanks.
