I made this with wood cut from a dead mesquite out back. It has been dead for a long while and was very dry wood.
Each square is about 1.5". Overall it is 9x12. This is after the first coat of butcher block conditioner. I will put 3 more coats on it to get it seasoned right.
There are some spots that look like gaps or cracks but it is just really dark areas of the wood.
If the enemy is in range, then so are you.
