I took the flower design from the center of the quilt and replicated it randomly throughout the background. Then I echoed everything, the flowers and the applique pieces.
In the center, I quilted around the small white flower center, the outside of the pink petals, and the outside of the black petals. She used a 1/2-5/8 inch batting, so the center fluffed up beautifully. I did not quilt on any of the rest of the pink applique pieces, so they puffed up a lot, as well.
