This is can be combined with Custom Engraving to make visible signage. Or simply allows you to look at your board naturally, as in the tradition of Chinese Picture Stones.
If I do this to a coaster or trivet, I will switch the feet from cork, to clear silicone bumpers like I use on the Charcuterie Board. This allows your new feet to stand taller than the bracket, and let’s you use your wall hanging on a flat tabletop surface.
I generally orient the stone, but you are welcome to communicate your preference via email. The saw-tooth pattern of the hanging bracket allows for micro adjustments to keep it level.
