Beveled both edges (deeper on the very bottom for more of a shadow line) and will ease the sharp corners tomorrow once the glue dries.
Next will be figuring out the screw placement to attach the base to the box, and then attaching the cross to the top. Considering using CA glue for that...or maybe should just stick with Titebond (as always open to suggestions).
Getting there slowly but surely. Looking forward to putting on the finish as I'm really liking the board he picked (hard to go wrong with walnut!).
