I made this box card from a pack of paper I had picked up on a shopping spree. Used Cricut cartridge Create a Critter 2 and thought it made a lovely Valentines card. It has an 'envelope' on the back that can be opened and a special message inserted. It is 6x6 when folded down so fits nicely into an envelope made on the 'envelope punch board'. The pics are of it closed, open, and the back.
