Make Perfect Pinwheels Every Time!

I love the pinwheel block. It’s a timeless classic that can easily be incorporated into traditional as well as modern quilt designs, but piecing all those little triangles is a pain. Below is a quick method for making any size Pinwheel block you need.

FORMULA FOR QUICK PINWHEELS

Note: The finished block size is the size of the block after the quilt is finished.

1. Determine the finished block size, e.g. 6 inches
2. Divide the finished block size by 1.41. (6 ÷ 1.41 = 4.25)
3. Add this result to 0.875 (4.25 + 0.875 = 5.13)
4. Round up the above result to the nearest 0.125 inches. (5.13 + 0.125 = 5.25")
5. The parent size squares will be 5.25"
6. Square up your block to the correct unfinished size (finished size plus 1/2")
