keepsake guest book

I'm always looking for create ways my brides can create a guest book that is truly a keepsake. Here's an idea: Family tree with your guests finger prints. Each guests signs their name next to their finger print. Maybe you have a family member who can draw or paint a tree for you. All the more reason to frame and hang on your wall. Do you have a great idea for keepsake guestbook?
