I don't think it is from Rings That Bind. I've seen it used for faux cathederal window denim quilts where you use a plastic lid for the circle and for an "I Spy" quilt from Fons & Porter. Fons & Porter sells a two piece template set called "Peek-a-Boo" that inserts a square inside the circle. Last year, seems like sometime around Thanksgiving, a quilter posted something similar to what you asked about, but it looked like magnolia blossoms. Some that she did were red one side, white the other. Perhaps they would be in the Tutorials.
