To make your own, you will need the following supplies: Black foam board (got mine at Dollar Tree for $1) Box cutter Circular shaped object to cut around (I just turned my office trashcan upside down and started cutting!) 8 ball shaped objects to represent moon (ideas: ping pong balls [use black sharpie], Styrofoam balls (paint with black acrylic paint and sponge brush, wooden balls, etc....) Hot glue gun 1 ball to represent the Sun (larger than moon ball) This is optional; you could always just write "Sun" on one side of the board with a paint pen, but I think the added visual is great!
