I love this idea. An envelope guest book. You just take a store-bought scrapbook/album and glue envelopes into it. Lay out colored pieces of paper for guests to jot notes down on, and then they can place them in the envelopes.
This would cute converted over to a scrapbook page. Original pinner said: Baby Map Picture - This would be easy to make! Shadow box, map of birth location, scrapbook paper or cardstock, and a printer or cricut for your letters and numbers.
In this box I will lay the little tooth I lost today…Please dear ToothFairy while I sleep leave me a coin…My tooth you can keep. Tooth fairy box…no more trying to find that ziplock bag under the pillow.
