I mounted the two paintings to Ampersand Clayboard. I first covered the sides of the wood cradle to protect it from the medium. Then I dampen the back of watercolor paper and apply a generous layer of soft gel medium to the clayboard. I lay the paper over the clayboard and press out any air bubbles. Because the paper and clay are absorbent, they soak up the medium and form a firm bond. I let the painting dry overnight, face down, keeping something heavy (in this case a brick) on the back.
