Then I took this old paint I have. Super glob, half evaporated, thick paint full of rust and can bits...the best! I smeared it on the ceiling nice an thick.
Then I added some silver and rust stains. I think I'll paint the rosette with color. Now I have to design the light fixture. It probably won't be a dramatic chandelier since the ceiling is pretty low. So I'm looking for some little bobble I can turn into a fixture.
