Pinch off about a half inch chunk of polymer clay. Knead the portion you broke off until it is nice and soft, then roll it into a ball. Press the flat side of a glass aquarium rock down onto the ball of clay until the glass is half way into the clay. The bulging side of the glass should be facing up. Do not press too far down, you just want to make an indent. Take the bead out. Prepare seven more picture frames in this way.
In our next step, we will put the photo in the bead.
