File this one under "Why Didn't We Think of This Before?" In a revelation that seemed so obvious, we felt silly for not doing it earlier, we decorated our home for Halloween with chalk. As we were putting up our scarecrows and spooky spiders, my son grabbed his bucket of chalk that sits on the porch and began decorating our stairs and porch with bats, witches and ghosts.
Excitedly, he exclaimed "Let's do the stairs, too!" We were able to go wild and draw all over our stairs and porch and knew that with the next rain, we could start a different pattern and begin our decorations anew. Fun, affordable and easy to clean up. Nothing scary about that.
