Better than a guest book, sign the canvas! I really like this idea! Use an engagement photo and then have a big party for first anniversary and get everyone to do it again on a wedding photo canvas to go alongside the original!
This Personalized Guest Book Frame displays guest signatures and a photo on a white mat inside a sleek wood border. Each of these guest book frames can be personalized at no charge to create an anniversary, retirement, or wedding guest book frame!
Guests throw darts at balloons with paint inside. You keep the art. :) This is such a fun Idea. You choose the colors and the size to coordinate with your style - might be more enduring than having a fingerprint tree in your house forever.
