How freakin' cute is this? Jason Permenter on Pinterest. Here's a closer look: This couple—inspired by this poster—used their fingerprint heart, made by overlapping prints of their left ring fingers, as an engagement announcement {Yes, it should be "were" not "we're"! }, but I think it would also make a fab save-the-date. You'd just have to make the little heart, scan it, and put some text over the background. Then you could print it at home almost for free. LOVE! Would you send out a save-the-date with a fingerprint heart?
