Engraving on a curved surface - barrel stave

Hello - just wondering if any starting points for how to engrave on a curved surface - looking specifically how to say engrave circle pockets in a barrel stave - to make a beer/whiskey flight. Would I need CCPro for this? Thanks. Erik

Carving on an arched whiskey barrel stave

I want to put text on some staves I have been saving. Is it all trial and error or a specific method to go about this? I have plenty and don’t mind messing up a few but would rather succeed sooner rather than later. Thanks in advance for any advice. Brian

If using CC Pro, then the design will be adapted to the 3D model.
