Cover popcorn or other ugly textured ceilings - I love this idea! We only need this in the dining room. The rest of our rooms have flat ceilings. Our dining room has the highest ceiling in the house and would be lovely to accent with this.
Styrofoam ceiling tiles - glues right over popcorn ceilings, and looks soooo coool. Good way to get rid of ugly popcorn ceilings without having to go through all of that work of scraping it off! Plus it would be like an added layer of insulation.
put a frame around thermostat, what a good idea, my thermostat is in the middle of my hallway where i have many picture frames, always hated that it was there, now i wish i had thought of that! Off to Hobby Lobby.
