ABSTRACT:
A hexaflexagon or an interchangeable face device is made by first printing a desired pattern on both sides of a sheet of card stock. The printed sheet is then die cut to form a series of parallel rows of zigzag slots. The slotted sheet is then laminated on both sides with a clear, flexible sheet material such as mylar forming a sandwich. The sandwich is then cut to form rows of alternating triangles. A triangle row is then folded and the two end triangles of the row adhered together to form the hexaflexagon.
