Something I did for my wedding was a wedding tree sign in board. It looks so cute and everyone has fun doing it. What you do is have each guest stamp their finger print on a bare tree so it looks like a leaf and then have them sign their name directly underneath it. You can even make a special one just for family members and have it be your “family tree.” Decorate it with some flowers from your wedding and display it on your wall. This is sure to be a family heirloom your future kids and grand kids will be fighting over years down the road!
