Can you use pantographs with your sweet sixteen? The panto that comes to my mind for this one is spiral squares. When quilted it takes on an interesting diamond shape but would not distract from the quilt itself. I am a professional long arm quilter and of the opinion that the quilting should enhance the quilt but the quilting itself should not be the first thing you see when looking at the quilt, or in other words, detract from the piecing and colors in the quilt.
