Spell Your Name with Bottle Caps!
I use to be a Resident Assistant in the dorms at my college. One of our "jobs" was to make door decorations (i.e. Door Decs) for each of our residents with their name on it.
We had metal doors so many of us crafty RAs used magnets and made magnets for our residents.
It was multi-functional door decs!
Lay out the bottle caps on some newspaper or cardboard and evenly spray paint the caps.
Once the caps are dry, stick one letter sticker on each cap to spell out your name, Sorority/Fraternity letters, the alphabet, silly words, etc.
