Here is a similar ball and the quilt I made and named Mirror Ball Dots. It is a simple quilt using 4" Pinwheels and simple Square on Square blocks with appliqué circles. A four patch border with smaller circles randomly scattered frame the center. Little did I know that many years later I would design a Square on Square Trim Tool for Creative Grids that would make both blocks. I used water glasses as templates to make the appliqué circles.
