Hi everybody, I recently ordered a projector (Panny 900) and am now looking into making my own screen. I already got a (semi- constructed) framework, but would I need to attach this frame to a board or not? The guy does use one on this site: http://reviews.cnet.com/4520-11247_7....html?tag=tnav , but I wonder if it's necessary. Also, what would be the best way to attach these two elements (nails, screws, glue)? Finally, I got some nice white blackout cloth for the projection surface, but the backside of this is slightly grey-ish, and I was thinking that perhaps I could use this side as well, for added gain. (I can make my room almost pitch black, so that's not an issue, but my walls are white...). Would that be recommended? Thanks for anything you can tell me. Bart.
