THE CHALLENGE: Create your very own Golden Rectangle Icosahedron!

(Yes, I absolutely meant “rectangle”, but twitter doesn’t give you an edit button.)

Use grid paper. (Or not? Might be a neat wonky one if you don’t?)

Start with a 1×1 square and another next to it.

Using a 2 unit long side, create a 2×2 square.

Then a 3×3, etc.

When it’s as large as you like, draw connected quarter circles to form your spiral!

MATERIALS NEEDED: Paper, pencil. If you have grid paper, that might help, and here is some special grid paper you can use courtesy of Justin Aion.

Here is a visual set of instructions, and below that is a video tutorial.
