I am doing "UStamp with Dawn and Friends - with Love 2010" at the moment (wow that's bit of a mouthful - check it out here). A lot of the projects this time have a Valentine theme, but they can be adjusted for other things too.
This project was called a Card in a Box and was created by the talented Jenny Moors (check out her blog here).
You can put a small treat inside the box and when you open it, it opens up to be flat. I used Stampin' Up's new Designer Series Paper - Kaleidoscope (which is available in the Summer Mini Catalogue), and the Sale-A-Bration stamp set Whimsical Words. I punched out some flowers using the Boho Blossoms punch to decorate the outside.
You could easily mix it up to put messages or photos on the other panels.
