Here is the front of the card. Fairly simple. Love the embossing folder. The stamp is from Stampin Up. I punched it out with a Stampin Up punch.
The inside was a pop up. I did it with a pop-n-cut die.
Here is a side view.
This is a card in the box card. It folds flat in the envelope. Kind of amazing. Here is a link to a tutorial. Not the one a I used but one like it. http://monicas-passions.blogspot.com/2013/10/card-in-box-video-tutorial.html This is one of the original ones. Mine is smaller to fit in a smaller envelope.
Most of the punches and stamps are Stampin up. Last year, I got a set of heart stamps with a matching die from Archivers. The set is by Hero Arts called Stamp & Cut.
The card in a box took a long time to put together so I did a simple Christmas card. The stamp and die are from Stampin Up. The paper came from Tuesday Morning.
