4. Take one of the potato halves. Use a pencil to scratch a simple design in the center of the cut side of the potato. Use the tip of a spoon to scoop out the parts around your design. Only the raised parts of the potato will print.

5. Dip the raised design into the paint. Now press the design onto the shelf paper. You can press the design onto the paper two or three times before you have to dip it in the paint again. Use the other half of the potato to make a different design.

6. You can also print with half of a grapefruit, a lemon, or an orange. Ask a grown-up to help you scoop out each section of the fruit. Try to leave the thin skin, or membrane, between each section. Squeeze out as much juice as you can. Then wipe out each section of the fruit with a paper towel. Dip the cut part of the fruit into the paint. Then print the same way you printed with the potato.
