I did the quilt top for a challenge for an Art group years ago. It was a fun challenge of piecing odd pieces randomly and applying them. I decided they needed the circles on top and then yarn couched to the edges with a zigzag.
I finally quilted it heavily using colors to blend with each piece and leaving the circles unquilted, so they stand out. The binding method is a faced edge so that none of it shows on the front. Sorry that the flash washed out the detail shot.
