I further researched the decoupaged quotes art car idea and didn't find a good sealant that I thought would work, so we're on to Art Car v3 -- covering the car in bottle caps. When I was little, I collected bottle caps, and my dad found them in the garage attic this summer and brought them to me. I was very excited to sort through them and think about what I could make with them now, and we have plans for further bottle cap art after the car is complete.
A week and a half ago, Steph and I went to dinner at Ralph's Great Divide with Dan and Douglas. While we were there, we thought to ask them to save bottle caps for us. Our server gave us about 200 that were still in the cap catcher under their bottle opener, and I stopped in last night and picked up another 330. A box of 4000 caps from eBay should be arriving soon.
The bottle caps are sorted by color, although I haven't figured out yet what design I want to make on the car. The caps are divided into containers of blacks, golds, whites, greens, yellows, blues, silvers, and reds.
