Thank you so much. The close up of the center rose shows the stitch. It's a simple L stitch with a reverse every other row. I did it by accident on the first quilt and loved the results so much that I used it on this quilt. It's easier if you have even circles to guide you, but if you are OCD about measurements, you shouldn't have any problem. The stitch has been copyrighted via the State Fair (I documented the creation of the stitch in my quilt description), and other public forums where I uploaded the photos of it.
