the link you have is NOT the same pinwheel, a pretty pinwheel but more complex.

Continuing. Break the block down into small squares. For instance the lower left simple block is a black and light green triangle in upper left corner with a pink and black triangle in the lower right corner.

The black/green can be cut from a larger HST (easiest way)
The lower right triangle is a right angle triangle in pink with a black strip to finish it out to the same size triangle as the black/green triangle. Mary and Mary Ann added a rectangular strip to the side of the pink triangle-------------then trimmed out the triangle, rather that trying to cut a quadrilateral just the exact size.

Like eating an elephant--------------one bite at a time.

Looks like the same design as Kaleidscope Pinwheel in the original Stack-n-Whack pattern from Bethany Renolds. However it is not a kaleidscope arrangement. So guess one would call it the basic pinwheel design.

Missouri quilt company has a YouTube video I just watched it

I know it as kaleidescope, also stack and whack and saw blade. All of those names also refer to other patterns, unfortunately.

You cut squares into 8 pieces, as I have shown in grey and white. You can do this with stacked squares. If you do, I strongly suggest you run basting stitches or pin well before you cut. The darker grey pieces I've shown are background. for a true kaleidescope, you need to be very careful in lining up your layers.

Missouri Star Quilt Company has a tutorial on it, I think it's called stack and wack.

Thanks, everybody!! I love being able to rely on you for help!
