My husband took me on an origami paper shopping spree for my Christmas gift last December, so I picked out several sheets of beautiful Washi paper. I decided to make this modular cube:
It's a Tomoko Fusé design from one of her many origami books. The book is called Cranes and Fans, and it's only in Japanese as far as I know.
While the edges of the cube are constructed from washi paper, the faces are constructed from TANT origami paper, which differs from standard origami paper in three ways: it's thicker, textured, and colored on both sides. I like it a whole lot better than standard origami paper for such 3D structures that contain so much open space, because the thicker paper helps to stabilize the model.
This model uses 12 sheets of washi and 6 sheets of TANT paper, each at 4 inches square. It holds its shape well without adhesives.
Have you tried a new material within the past few months? How did it work out?
