Perhaps, as the weekend has produced this 14inch square. Cotton, two layers of 80:20 wadding, 60 weight thread. All white stitching on one side, and mixed white and blue stitching on the other. I marked the circles, the grids and the main radiating lines with washable blue pen and quilted them with the walking foot. I then just quilted the rest freeform. It has still to be trimmed to its final size. Looking at it with a critical eye, it would be more balanced by lining up the middle row of diamonds with the very base of the circles, but live and learn.
