I think the only problem is color placement. If you alternate light/dark on your fabrics, each card would show up more. I personally think scrappy is "magic".. you can combine the strangest fabrics you own, and while an individual block might not shine by itself it seems to work once they're all in a quilt. My quilt buddies are always amazed what I do with their "ugly" scraps or yardage.. and I don't do anything more than balance the colors!
