Gather fruits and veggies, ideally those that are already past their expiration date. Fruits you can use include apples, pears, oranges, bananas and lemons. Vegetables like broccoli, cauliflower, bell peppers, brussel sprouts, potatoes, carrots, corn, mushrooms, bok choy, snow peas and okra make wonderful prints. Clean the fruits and vegetables. Wash and wipe them dry.
Prepare your paper or fabric. Cut it into the desired size.
Put different colors of paint in shallow plates or containers. Use tempera or poster paint if you are printing on paper. For fabric, go with acrylic paint or fabric paint. Add some water but do not water down too much. Mix well.
