Parental supervision is recommended.
If you are going to make your prints on paper, use washable poster paint for good results. You can cut them in half through the stem, dip them in red and green paint, and make a very nice-looking collage of apple shapes. Cutting them through the middle makes a circle stamp with a star in the middle. To make dark green paint, add a little black paint at a time to some green paint. You can also make a fun gift for a parent, grandparent or caregiver by brushing the paint onto the children's hands and decorating the shirt or tote with those special handprints.
