Sewbizgirl, flip the map!! What a good idea. My mind isn't in a rut, it's a trench. Another idea that a person on this site mentioned was: "If you have a self healing cutting mat it needs to be re hydrated to stay self healing. When the moisture is gone the mat dries out and will have cut marks and dull your blade. Soak the mat in room temp water for about and hour, let dry. That's all you have to. The mat will be soft and be like new again."
