First take two cardboard boxes in the shape of cubes and make sure they are taped shut. Choose one solid color and paint all 6 sides. (I used exterior house paint to enhance the durability)

The last step is to use white, squeezable fabric paint and make circles on each facade. Then use a small to medium size paint brush to fill in the circles. Once dry its time to play!!!

This is what the boxes should look like AFTER all the sides have dried.
