I bought my ruler/template for that exact quilt at my LQS. Mine makes a 47" 40 blade center medallion. Here is a photo of mine. It is put out by Marilyn Doheny and is a 25", nine degree that also had an extension available for an even bigger medallion! My colors were much brighter, but I was using a new camera and did not know how to turn off the effect yet. Lol!
