She's probably telling you she doesn't want a traditional quilt pattern, but a modern one; many, many of the younger generation prefer the 'new' look -- I remember the Pucci prints from when I was late teens/early twenties.
If you google "modern quilts in gray and white" or "neutral color modern quilts" or even just "modern quilts" you'll get a whole lot of easy but dramatic ideas.
Good luck, Mom; this way of quilting can be hard on some of us long time quilters!
