To make this organizer first take four tp rolls and apply polymer adhesive to them one by one using a brush. Then apply a paste of modeling clay on the tp rolls to give a rough reef like appearance. Then using metallic toned acrylic paints paint the tp rolls. With a hot glue gun fix the painted rolls on a piece of cardboard. After that using polymer clay make different things like fish and sea rocks. Paint them too with acrylic paints and stick them to the rolls and the cardboard base with hot glue gun. Also hot glue some sprigs of artificial plants. Your coral reef pen holder is ready.
