My daughter using black paint to draw her own stripes, antennas, wings and eyes to turn them into bees.
Alternatively, you can use a marker to draw the stripes, antennas, wings and eyes.
Have your kids paint one of their hands grey then press their hands on paper. But my daughter wants her elephant red, that's fine for me. I don't limit her imagination. Then let the kids draw eyes, ears, tail and tusks on the elephant using marker pens/crayons. Ta-dah! Here is her handprint red elephant!
