We've seen fingerprint tree guest books, and we've seen wooden guest books, but now we've seen what happens when you combine them: a wooden guest tree! Lola and Jimmy DIYed the tree and all its little leaves to make this amazing memento. And, of course, guests were encouraged to "leaf" a signature.
If you're handy with DIY, definitely try this out; otherwise Etsy's got you covered.
MOAR guest book ideas await you!
