Hoogeboom's work is ceramic (clay and glaze). You can use ceramic for your memento.
Hoogeboom's work inspires other materials as well. For instance paper forms can be made with the Arches paper in your kit and gesso. Small pieces of wood can be bonded together to make one form. Bond wood with simple materials such as glue, gesso, paint.
