Here's the link that I found to a Mosaic Pinwheel on Sprucecrafts ...
https://www.thesprucecrafts.com/mosa...attern-2821194
.... however, it is a different pattern than the photo that
DRoberts' has posted above.
I checked QuiltersCache.com, but there are none the listed as Mosaic or Pinwheel that match up.
Sorry, I'm no real help to you.
..... if I like a block, I just make it, and enjoy!
