Inspiration #78: A Blank Canvas Goes "Up"

I got a pair of blank canvases at Michael's tonight for only $6. I had thought I'd make a guest book tree like the one inspired by this awesome wedding, but I had another idea. What if the thumbprints were balloons? [I'm sure you saw the sweet engagement session posted on Green Wedding Shoes and Wedding Chicks shot by Wildflowers Photography!]

Should I trademark my idea? ;)
