In some instances you may not want a rectangular shaped mat. Unfortunately, most of those situations are so unpredictable/specialized that ultimately you will be left on your own to do the mat cutting job. On the other hand, customizing the mat at the location ensures a perfect fit. Under this category you will find some oval shaped mats and some mats that you can cut and purchase nosing and glue it on site. For grates and custom foyer matting look at the “Recessed Foyer” mats section.
