9 Molecule Origami Windmill Base Tessellation

An origami tessellation using the windmill base folded nine times on a single sheet of paper. More could certainly be done with the resultant collapse. Still it has a nice appearance as is. There's no trick to folding it. Just divide your paper into as many molecules as you want and fold a windmill base in each What you do from there is up to your own imagination. I found it easiest to work the corners first and then move inward.
