These dummy cake tops are interchangable. The tops can be removed and exchanged to show whatever course I'm advertising. The course I cake has roses, sweet peas, leaves and shell border on it. The course II cake is a basketweave cake with a rope border. The course III cake top is covered in fondant and has fondant roses and leaves with a fondant bead border. These cakes will be displayed at the Orem Roberts store to promote my Wilton Cake Decorating Classes.
