Im going to show you how to turn this into a chess board!
Step 1: Prep
Buy the size board you want with a little bit extra on the sides.
Step 2: Carve
Carve or burn lines into the edges to create the different squares.
Step 3: Clean
Sand the front side of the board to clean off all the rough edges and apply a pre stain so that the later stains apply evenly.
Step 4: Stain
Finally, add a desired stain to alternating squares to create a checkered pattern.
