What you need:
Water colors (red & green)
Draw a yuletide motif on white paper, cut out and place on a dry sponge (one with tiny holes in the sponge are the best).
Then trace the pattern with your ballpoint pen and cut out the shape.
Then, dip in paint, squeeze excess paint out and blot onto either plain white or solid colored wrapping paper.
You can stamp each sponge several times before re-dipping in the paint.
