I worked with 6” squares, instead of 2”& 1/2” sq., for the large pinwheels and 3” sq. for the smaller. You can use any size you wish, but you need to remember that the block will finish 1/2” smaller. If you would want a 6” finished block, you would start with 6”& 1/2” squares. I’m not sure I would make the pinwheels any larger than this, as they get a bit “floppy”. Mine will be tacked down at one point as soon as I’m done with the quilting.
If you have any questions, just let me know. The above directions were gotten at a quilt shop in a little kit but Moda Bake Shop has a quilt with the same idea here.
The above image is from the Moda site and their version.
Happy “stash busting”!!!!!!!!!!
