The Pop-up of All Pop-Ups

Today is my best friend's (practically my sister), my mind reader's, and future maid of honor's birthday. Every year I try to do something really special for her. In past years I've done full size chalk drawings on the sidewalk, outside her bedroom window of Mickey Mouse and other characters wishing her a "Happy Birthday." Unfortunately, you get older and well, your back isn't up for it as much anymore. So this year I made her a pop-up card.
