I am in love with these cupcake gift boxes. They're just so stinkin' cute! They're made with paper mache boxes, foam balls cut in half, fabric, and a glue gun. It seems pretty simple! And there are so many possibilities. In addition to adding fabric to form the frosting, you could paint the boxes to look like cupcake liners. Or make your own to go around the boxes like in the picture above.
