Download the Pattern Below
Each tablet is 11.5" tall. In the simulated image above I am showing each tablet with a backer board.
The simulated backer board is different color wood. In real life, you could use the same wood for the backer. The shadows will highlight the letters. For strength, Baltic birch plywood would be a good choice.
This cut will probably take a couple sittings. The first tablet has 214 interior cuts. The second tablet has 147 interior cuts.
This post was edited to correct a typo in the original pattern. The pattern has now been corrected.
