I saw this somewhere, so it is not my idea, but this particular one is my design. You can download a PDF file with directions
HERE.The directions include making the one here (structure only, not stamping!) and also how to make one with a solid clear box top.
These make great Christmas or anytime gifts!
And I had so much fun making them that I made another. This one is much sturdier as I made the bottom of the box out of the single layer white cardboard that comes in a pack of designer series paper.
