I am moving this thread to the Advanced/DIY area. I have know some others to make their screens and use this material as well.

FYI, "gesso" is like a primer that oil painters paint over thier canvases to get the oil paint to stick to it. Without gesso, over time, the oil paint will crack and peel off. It dries to a nice matte white finish. If applied smoothly [ie rolled on] I can see this working well. If you go to a local artist store, im sure you can get more info about it and some small containers to do some sample tests.

They sell Gesso at Michael's stores found in many cities. A friend painted his blackout fabric with a white/gray pearlescent mix and it was a noticeable improvement. Use the gray sparingly -- while it improves blacks, it can reduce your color punch.
