Then I thought it needed a little more contrast and I added a 3 inch band of darker grey on one side.
I machine quilted the whole piece with straight lines, trying to emphasize the movement I could see in the fabric.
Next came embroidery time! I had picked yellow and green threads for this because I wanted to take inspiration from this picture. But after several attempts, I had to admit that I couldn't find a green that would show well on both fabrics. I turned to a variegated red-pink-orange thread that did work much better.
