The concept is simple. Instead of offering guests the traditional method of signing their attendance, a sketch or outline of a tree is set up for guests to "thumbprint" and write their names beside. They will get a kick out of the uniqueness and at the end of the day, you'll have a visual masterpiece (instead of a book full of plain signatures) to remember sharing your big day with family and friends. Who wouldn't love this idea!
Thumbprint trees are a clever way to add a little color to your overall theme without sacrificing the elegance of the day. It's often the smallest design details that guests will remember forever. Take advantage of the opportunity and wow them from the beginning :)
