Here gain you have to get crafty with the custom wooden lengths and boards to build this unique model of wooden park bench! Step 4. But remember that all elements of the bench must be on parallel lines. This can be achieved by drawing a kind of upside-down trapezoid shape for the chest, and two vertical lines for the abdominal trunk. The base and the legs of the bench are brown, but the top is a colorful rainbow of flair that will stand out amongst your plants. The bench is 5' long and stands just over 1.5' off the ground.
