On November 28th, 2021, I will have the pleasure of giving an online origami workshop at the Birmingham Mini-Meeting. We will fold my Whirlwind Box. This pattern can also be tessellated. Be sure to prepare a 16×16 grid on a square of copy paper, Tant, or other thick paper. Kami goes as well, but is not as good.
In the pictures you can see the box folded in two ways: the easier version using the full grid, which we will fold in the workshop, and a clean fold made without the grid.
