Roll out the air clay or play dough to a smooth thin layer.
Place a bowl upside-down on top of the clay, and cut around the bowl to create a circle.
Stamp the clay using a pre-made stamp or carve out by hand. Include ink to add colors.
Take the clay circle and gently set into the small bowl to form the bowl shape of the diya. Add small beads for decoration. Allow clay to dry overnight.
Once dry, paint the bowl for added decoration. Add the candle to the diya and illuminate.
