Using a 3×12" straight-line long-arm quilting ruler to keep their lines perfect, Handi Quilter studio educators Vicki Hoth and Marie Eldredge stitched pairs of concentric lines behind the pinwheels so the pinwheels look like spinning fan blades. While most of the quilting was done in white thread, coral thread was used in some areas for contrast. They stitched a Greek-key design in the inner border and a continuous chevron in the outer border to finish the piece with a flourish.
