I thought of today's technique while I was out walking and enjoying the full pre-dawn moon. The craters looked like cells on a sponge, so when I got back to the studio, I made a stamped "moon" using an old cellulose sponge cut with a paper cutter to make a flat surface. I applied white stamp pad ink and stamped through a circular template - aha - a moon! Probably not original, but entertaining :) And it reminds me of the early morning moon.
