I made this for my family on Shutterfly and my whole family is just LOVING it! When somebody finds it, they write a message (or draw a doodle if they can’t write yet), then hide it for someone else to find! *I* love that it is encouraging them to write and be creative without any nagging from mom! Click on THIS LINK to go to Shutterfly, edit with your family’s last name, and save it to your account. Then you can order it, or wait for a sale/deal — I got mine for free, and I’m sure you can too if you wait for the right coupon code!
