Autumn leaves is an arrangement of Shuzo Fujimoto's clover tessellation. It uses 4 different size clover tiles. It requires a 30 division grid with 30 diagonal divisions. You need to come to class with the paper pre-gridded. The easiest way to make the grid is to fold a 32 division grid and cut it down to 30.
If you are experienced with tessellations you can fold with 15 cm kami (like Mr. E does) or you may want to try larger paper such as 10" or 24 cm. Printer paper will work well with a square cut from a piece of A4 or letter (8.5x11")
