When it's all done, we'll give it a thorough review.We will break down the process into 5 easy steps to help you understand how to make a projector screen.

If you're hell-bent on doing all the research yourself, there are couple of places to check out. The real question: is it worth it? Since you might be a little leery of dropping several hundred dollars on parts and gutting a nice display because people you don't know on an online forum said so, we're going to do it for you.
