I have bedroom curtains (double set - one rubber-backed and one sheer) that are letting in too much light where the light sneaks over the top of the curtains. The windows extend to the ceiling. The curtain rails are hung from the ceiling (similar to this installation lifted from this blog).
I'm planning on installing a pelmet, that extends to the ceiling, painted black on the inside (facing the curtains/window), and I think that will cut out a lot of the light. However, there is still a lot of light that hits the ceiling, and then bounces down between the two curtains and gives them a glow.
I'm thinking if I paint the strip of (plasterboard) ceiling between the pelmet and the window a matte black, that should help cut out a lot of those reflections.
However, I have been warned that if I do that, if I ever redecorate the room and remove the pelmet, I will not be able to paint over the black paint and restore it to its white colour.
My questions are:
If I paint part of the ceiling black, am I really making myself a problem later if I decide to restore it?
Is there another way to make the ceiling black on a more temporary basis? (I figure black Contact is not the way to go!)
