The Dresden Plate was the focus of the last two episodes of Sewing with Nancy and they had many different size centers, no matter what size the blades were. I don't think this is one of the "rules" of quilting, so I think yours will be just fine no matter what size they are! Your quilt, your choice!!! Please post pictures when you are all finished with this lovely quilt!
P.S. I also heard that the Quilt Police were banned from this site :thumbup:
