I have used rear projection onto a shower curtain for hallowindow.
But I want to try to rear project atmosfearfx's bleeding walls.
the problem here is the rear projection material needs to look like a wall. not just a white backdrop.

so i though maybe I could try the woodgrain painting methhod.
just not sure how it would take to the vinyl curtain material.

I was looking at some curtains. Some have a pattern that looks a little like wall paper.

since there is a delicate balance of thickness of material suitable for rear projection.
I am prone to stick with what works. I know the shower curtain works well w/rear projection.
but dont know about painting it.

what have you been successful with?
what dosent work?
