Designer: Francesco Mancini
Diagrammer: Francesco Decio
Details: The diagram shows how to fold a rectangular box with an heart on one side from a single square of paper. The design has a color-change approach so you will end with the heart colored differently from the box. You can connect more boxes by inserting the heart of one box on the side of another one.
Meterial: Works fine with any kind of duo-color paper. Best result with foil.
Size: Starting from a 15 cm square you'll have a box measuring 5.5x2.75x2.75 cm
