Here are some videos on how you would go about building a corn hole board and create the toss bags if are a do it yourselfer and do not want to purchase one.
As explained in the u tube video bellow, a corn hole board is built with two pieces of hard flat plywood and two front legs for ground support and a wide top center hole. You can purchase the wood at any lumber store like Home DePot or Lowes.
The u tube video above explains the process of making the corn hole bags which you need a total of eight. The
cloth is purchased at any fabric store and a bag of corn( which I think that’s how the game got its name) or you can get away with a bag of beans which you can get at any grocery store.
