Fill the fastener holes with wood filler, sand the pieces, and coat them with primer. This will cover knots, seal the wood, and make the colors pop. Spray the lid and base in two different colors. Once the paint is dry, tape off color-coded strips on the base dividers to indicate each team's goal, as shown. Spray the strips and remove the tape. Spray paint groups of 30 bamboo stakes in each of the three colors.
