I love the look of white on white quilting- white thread, white fabric.... the texture of the quilting really stands out. Here is a great example of this, with these pictures of a Dresden Plate quilt that I quilted lately.
I did the crosshatching with the Intelliquilter, and the feathers are freehand. The blades of the plates are stitched down using clear monofilament thread using a tiny serpentine stitch. I didn't want to take away from the fabrics in the plates.
