This is how I chose to quilt my flower heads. I felt they needed some emphasis and I've provided it with stitching throughout the petals and leaf veins.
I also felt that the lillies were missing something. The petals were so large that I decided what was missing was a vein up the middle. I added this simple stitch with an embroidery thread by hand. I think it makes a great visual difference even though its such a small, basic detail.
I'm nearly done now and I really do love the look and feel of Lily Rose. I can't wait to hang it up and enjoy it every day.
