Iso-Area Stars (CFW 291)

Images of finished model in back-light (without any actual instructions apart from the possibility to reverse-engineer the design) were published in Fujimoto’s book, Invitation to Creative Playing with Origami, on page 162.

I reverse-engineered this model and found it to be Iso-Area Square Twists, pursed (that is, you fold the edges of the central square in the twist to the corresponding axes of symmetry of the square, which forms an interlocking star).
