Upside down decoupage on a plate. 1. Turn the glass plate upside down, cut the paper towel or the rice paper by hand and place it with its good side towards the glass surface. 2. With a clean soft brush, apply a layer of decoupage glue on the napkin and always from the center to the outside radially. Wait for it to dry. 3. Apply white or beige acrylic paint on the area that is our napkin. Then, with the corresponding colors of our pattern, we passed it with a stamp or a sponge, mixing them lightly on the rest of the surface of our plate.4. After they dry, we apply a paint all over the surface. Wait for it to dry and apply 2 to 3 coats of water varnish for protection.
