Use stencils you already have, or make your own.
Sure, drawing outside with sidewalk chalk isn't a new idea, but try using stencils for a fun twist. Either use stencils that you already own, or make your own by tracing a shape onto a piece of construction board, cardboard, foam board - or anything else you have - and cutting it out. Print templates from various websites, or just trace the outside of an item in your house. Try new and different shapes like stars, flowers, bugs, street signs, and anything else you can imagine.
