If you do not have a drawing compass, place a thumbtack over the pencil mark you have made. Place a piece of string under the thumbtack and push the thumbtack down so it holds the string in place. With a ruler, measure 3 inches (7. 6 cm) away from the thumbtack, starting at the very center of the thumbtack. Tie a pencil to the string, making sure that the distance between the pencil tip and thumbtack is 3 inches (7. 6 cm). Draw your circle.
You can also cut the hole using a hole saw or a router.
If you are not familiar with using a mitre or hand saw, ask an employee at the lumberyard to cut your wood for you. Make sure you bring the correct measurements to the lumberyard.
Drill your holes with a drill bit that is slightly smaller than your screws. This ensures that your wood won’t split when you drill the screws in, and allows the screws to go into the wood more easily.
This intersection will be where the drill bolt goes.
If you decide not to do the traditional paint pattern, get creative! Use painters tape to create shapes that you can paint on or around. Use bright colors and make your cornhole board stand out in a crowd.
You can also use a needle and thread if you do not have a sewing machine.
If you do not have a digital baking scale, 2 cups of feed corn is very close to 15. 5 ounces. It may not be exact but it will be close enough. [15] X Research source
