My daughter wanted a headboard made from tin ceiling tiles.
I bought a sheet of plywood and gathered pieces of trim. I cut the plywood to size for a queen size headboard.
Instead of spending money on real tin tiles, I found 20" x 20" tiles made from Styrofoam. I bought two packs of four tiles for $2.50 each!
I placed the tiles on the plywood and used a variety of trim pieces to fill in the gaps. i have a power miter saw, but also used my old hand saw and miter box and then glued everything in place. I used water based glue and primer so as to not melt the Styrofoam.
Once the primer was dry I used silver paint to paint the whole thing per my daughter's request. Two 2x4's on the back will attach it to her bed frame. She lives in an apartment, so I can't secure it directly to the wall the way I would like to. She absolutely loves it!
Here's the headboard installed. We installed it high for a more dramatic appearance. The lighting in the room wasn't good, so the photo doesn't do it justice (this makes it look washed out and almost whitish, it's actually the silver pictured above). I've had MANY people ask where the tiles can be found. I bought these on Amazon.com.
