I apologize if I'm putting this in the wrong forum. Here's my question, I've read numerous other posts on DIY screens, it sounds like there are at least a dozen adequate ways to make one. I am a graphic artist at a sign shop and can get a 4'x8' sheet of a plastic material called styrene. It is lightweight and completely smooth with very little gloss. I was wondering if anyone else had tried this material, and if so, how were the results.
