10 years ago there were not any fun guest book ideas like this! I wish that instead of my fill-in-your-name-on-the-blank book that I had one of these colorful and fun prints from Personalized Prints for our guest book. The colors can all be customized along with names, dates and even monograms. My girlfriend did the fingerprint tree were guests filled out the tree by putting the fingerprints on the poster and then signed. What a memorable keepsake! You can find these and more ideas on Personalized Prints' Etsy site or their website at www.modernkeepsake.com.
