Most folders know about A4 paper and its 1 : √2 ratio, but fewer know about American letter paper and its special ratio of 4 : 3√3. In truth, that ratio hasn't got a lot of play, but it is a very excellent size for making Shuzo Fujimoto's regular tetrahedron.
Supplies:
It would be good if the student brings a sheet or two of 8.5" x 11" American letter paper. But I'll have a supply with me, if they forget.
Advisories:
- This uses non-square paper: American letter paper, 8.5" x 11"
