Wash a potato. Cut it in half. Draw a pattern on the cut surface of half potato. You can also draw another pattern on the other half. With a knife cut away any potato that is not part of the pattern. After you do this, the shape you are going to print will be raised from the rest of the potato. Cover the raised part with a light coat of poster paint. Lightly press the potato on a sheet of paper, when the pattern fades, paint the potato again. Finish by making stem n leaves using paintbrush.
