By day, this cityscape mural makes a great backdrop for playing with toy cars and trucks. When the sun goes down, all it takes is a night-light to illuminate the buildings and night sky.
First, make sure the wall you plan to decorate is clean and dry. Then pour a shallow layer of white wall paint into a flat-bottomed container (you need an opaque white undercoat to make the buildings clearly visible during daylight).
Dip one of the sponges into the paint to evenly coat its surface, then holding it upright, evenly press the sponge against the wall just above the baseboard to create a "building" imprint. You may want to practice on newspaper until you are able to achieve an effect you like.
Continue in this way, using all the sponges to stamp a row of buildings. You can even trim a sponge into a triangular roof or steeple shape or use a paintbrush to add finer details.
Once the paint is dry, use the same method to apply a topcoat of glow-in-the-dark paint to all the buildings.
Let the final coat dry thoroughly. Then attach the night-light and glow-in-the-dark stars to the wall.
