These ATC's were inspired by Hanna's blog post.. It appealed to me because of its serendipitous nature.
I'm not good at taking "in progress" photos, though, so I'll have to describe the process in words. First, I ripped up pink paper scraps and collaged them randomly to an 8 1/2" x 11" piece of cardboard. Then I cut the sheet into 10 ATC's and overstamped with a hand carved stamp. Fun!
