Technically, it's still summer but the stores are filling up with fall colors of orange, red, yellows, and and russets. And it won't be long till the leaves follow suit. Why not let the kids print and color these leaves in colors of the season. Use marker, crayons or pencils and when printed on tracing paper you the color will show through for a cool stained glass effect.
