It's amazing how just switching from paper to leaves can make painting new again. Both my children loved this project and didn't want to stop painting. They kept gathering leaves, painting, gathering leaves and so on.
I'm always saving various containers for craft projects. I used baby food jars for the water and ice-cream mochi containers for the paint.
For fun we scattered some leaves on the ground. I can't help but think of Gene Wilder singing "Pure Imagination" when I look at these leaves.
