Knotted Web

Knotted Web is a tricky tessellation with a non-standard arrangement of hexagon and triangle twists. It's the same on both sides (isoarea) and is designed to be folded from the center out, without precreasing.

The pattern repeats are aligned with the edges of the paper when you use a standard triangle grid on a hexagon, and you get to choose the size of the grid to match the number of repeats that you want to fold.
