Instead of having a traditional guestbook at your Mitzvah, how about having something that can not only showcase your personality but also be used again?
- furniture that everyone can sign
- lockers for some graffiti from your guests
- create a movie poster using your photo as the spotlight
- have your friends sign your favorite board game that can then be framed in your room
- using some of your favorite pics, make a quilt with square for everyone to sign
