Surface technique

It looks simple, and it is… except for the complicated parts. Make two-toned prefelt. Insert tiny glass marbles & secure with rubber bands. Needle-felt over base. Wet-felt. Needle-felt openings over marbles. Pop marbles out. Wet-felt again. Needle-felt again. See… nothing to it! 😉 *For reference, the marbles are 1/2″ diameter.
