Fingerprint guestbooks are a fun, modern, and increasingly popular alternative to traditional guestbooks. The idea is simple: Each guest “leaves” a fingerprint (leaf or balloon, depending on the type) on the guestbook and signs their name to it. When you’re done, you end up with a wonderful record which also makes a beautiful piece of art for your wall. You probably won’t flip through a traditional guestbook too many times, but a fingerprint guestbook will be viewed for years to come. We had one at our wedding and it is truly one of our favorite keepsakes.
