To build a cornhole board set, you need 2 pieces of 1/2 inch plywood 2 foot by 4 foot. The hole should be 9 inches down in the center of the plywood. You will need some 2X4s to construct the sides of the cornhole boards. Legs can be made to be stationary or fold-down like the attached pictures. Once you have completed your project, paint and apply your favorite team vinyl image. This is a fun project for the whole family.
