I got the idea for this box from some junk main one of my co-workers received. If you push down on it, it flattens out so that you can put it in an envelope, but when you take it out of the envelope it springs into a box shape. I thought it was just about the coolest thing I'd ever seen, so of course, I had to figure out how it was done. The secret is that it has a rubber band inside.
The box my co-worker received was hexagon shaped, but I thought it would be easier to start out with a square. Here's mine flattened out in my scanner:
I used Kaleidoscope Kreator 3 to print the graphics for the sides. Next time, I will make sure that the flowers on the top half of the box sides are right side up. Oops!
For the top, I punched out a square with my scalloped square punch, stamped Happy birthday and added some punch flowers.
And here's another view of it popped up:
