This is a high intermediate model—the steps are no more complicated than swivel folds—but it requires the student to fold precisely, to make folds that vary in sharpness along their length, and judge distances by eye, rather than via landmarks (e.g., dividing distances and angles in thirds by eye, or "make this distance over here equal to that distances over there." It also requires delicate shaping. Avoidance of unnecessary wrinkles and marks is key!
We will fold our model from foil (to do the shaping), as in the first image, but it is really designed to be wet-folded. The second image shows two examples wet-folded from custom Origamido paper by Michael LaFosse and Richard Alexander.
OrigamiUSA will supply paper, to be handed out by the teacher in class.
