About

This free heart box generator makes a curved heart-shaped box using a living hinge: a single flexible wall that bends around heart top and bottom plates. Because a heart curves everywhere, the whole wall is a living hinge. Tune the slit spacing to your material so the wall wraps smoothly, then glue the seam. Great for Valentine gifts, trinket boxes, and keepsakes.
