Pinwheel with color change

I came up with this model when playing around with hex twists. It’s quite simple so it may have been invented before. This pinwheel shows a nice color change and can be made (with minor modifications) from many different polygons, including: square, hexagon and octagon. You can also modify the width of the color-changed part or change the pursing pattern in the middle to achieve different variants.


I find the hexagonal version nicest. Two hexagonal pinwheels can be connected back-to-back using the flaps on the back of the twist.


Folding instructions to accompany the CP are as follows:

* start with a hexagonal grid (8 divisions in each direction)

* make hexagonal twist in the middle

* unfold flat

* valley-fold a one grid unit wide margin around the hexagon (3D, doesn’t lie flat)

* re-fold the hex twist, keeping the color-changed margin folded all the time

* purse the hexagon in the middle
