I have used W&N and W&W on ALL of my quilts, and have absolutely no desire to use anything else. I agree with AliKat - the quilt design decides how little or much quilting I do. I've done quilts with quilting 9" apart, and quilting 1/2" apart and the outcome is always the same - GREAT. If you think the whirlygig needs another line, do it. It will look wonderful!
