Tape the watercolor paper around all 4 sides to a board or old tile to paint on.
Wet the entire paper with water. Paint a warm color such as red, or pink across the top 1/3 of the painting for the background. Add a second color such as yellow or orange touching the first color. Tip the painting to allow the colors to mix. Let the water do the work.
While still wet, press a heart-shaped sponge or a wooden heart-shaped cookie cutter wrapped in tissue paper, on the painting to soak up paint. Allow to dry. This creates heart imprints.
When the background is dry, you can use it for several things:
1. Using glitter glue or acrylic paint, outline the shapes created on the background and paint a message in the heart shapes. Use smaller hearts for this.
2. When dry, you can also stamp the painting with white or red acrylic paint that has been painted on to a rubber stamp. The stamp can be simple or a purchased rubber craft stamp. Allow to dry.
3. When dry, you can use the paper to cut out large heart shapes to fold and paint a message onto to create watercolor valentines. Give the students several ideas to choose from. Mount on a larger white manilla tag paper for a solid folding card.
4. When dry, you can cut out smaller hearts to paste onto another watercolor background.
