This is a Valentine's day card I made for my wife to be from myself and our two kids. It consists of three cards that layer in with each other to make a 3 page greeting card. The first card says "Happy Valentine's Day", the next says "We love you Mommy" and the last has nothing written so that you can write a personal message. The message on the second card is hidden when the first card is closed. Someday I will possibly put this into a customizer so you can put your own messages, but for right now, nope.

Simply take three pipe cleaners (or whatever else) and run it through the 3 holes to create bindings.
