When we made my art room, it originally started out that I was going to have a big plain rom with lots of storage.
BUT, I have a wonderful husband who said I deserved more and so I ended up with the most beautiful and functional art room I can imagine.
When we did the drywall, on the ceiling, I decided since the room was so pretty, that I wanted faux tin and bought Styrofoam ceiling tiles to achieve the effect.
The installation was EASY PEASY!
we bought our paintable Styrofoam or styrene tiles from http://www.decorativeceilingtiles.netMy tiles were on sale for 2.99 a tile (Canadian) and are 20″ x 20″
