Not sure I understand. You mean you have completed the applique and are just looking for a way to finish the mat? You don't necessarily need batting or fusible if that's the case. You do probably want to use a backing fabric and binding. You could add a fusible to make the mat stiffer or a thin batting if you want to quilt around the design.
