This block could range in size from 8 inches to 12 inches. As you can see there are many ways to color this block. The simplest version on the left shows just the pinwheel on a plain background (called Version "A"). Or you may wish to emphasis the 4 squares at the blade of each pinwheel as shown on the right (Version "B").
See a quick version for assembling Version A here. Or, you may choose to use 12 squares and 4 half-square triangles to make each the block.
For review of making HST's in quick methods, see the Half Square Triangles article here. By counting how many combinations you need of each pair of fabrics you can "gang up" your HST's for faster sewing.
Here is the simple blank block above.
