Concentric circles in each block?
Green & black blocks full of circles, all the way to small in center of the block.
White embroidered block with the larger outer circles but stop before/outside the embroidery. One or two rows echo stitching up tight to the outer edge of your embroidery designs.
Concentric squares (with bowed in sides) in the leftover corner spaces between the blocks of concentric circles.
I don't know your quilting method. I hand quilt, so doing this would be fun and easy to customize in blocks and separate threads stopping and starting or traveling is easy with hand quilting.
