Pinwheel with Color Change — CP and folding instructions
This is the Crease Pattern (CP) and basic folding instructions for Pinwheel with Color Change designed in 2015 by Michał Kosmulski.
This is a simple model which can be folded from several different polygons. The version from hexagon is probably nicest, but you can certainly use a square, a hexagon, and an octagon. I’m not sure about pentagons, heptagons (odd number of sides) or polygons with more sides than eight. There is a color-change so the center has a different color than the blades of the pinwheel. The grid is 8 divisions in each of the principal directions. The Crease Pattern below is for the hexagonal version but version for other polygons are simple to deduce from it.
