Cut the apples. Slice apples in half from top to bottom. Pat the cut side dry with a paper towel to help the paint stick.
Pour the paint. Add red, green, and yellow paint to small trays or paper plates.
Dip the apple. Press the cut side of the apple gently into the paint.
Stamp the paper. Press the painted side onto paper to make a print. Lift carefully to reveal the apple shape.
Repeat and explore. Continue stamping with different colors. Kids can mix colors, overlap prints, or add stems and leaves with a paintbrush or marker once dry.
Let dry. Set the finished art aside until completely dry before displaying.
