Some say that one role of carving is to link and decorate transition areas. At the tang we have the breech transitioning to the wrist. At nose of comb, comb to wrist. Cheekpiece to buttstock. To me the best designs flow from an origin into another space. Certainly that is the case with carving behind a cheekpiece. It often flows from the “cliff edge” and uses that edge as part of the design. It’s the origin. Same with any carving, I think you want an origin and a sense of movement or flow into a new space. Maybe look at examples of Lancaster, York, Christian’s Spring guns with this concept in mind: origin, flow, transitions in the stock architecture.
