This is where most beginners get nervous. Let’s clear the air:

· Natural Ridges (Pattern):

o Shape: Curvy, flowing, and follows the walnut’s "grain."

o The Test: Try to poke a single hair or a brush bristle into it. If it doesn’t go in, it’s just a deep, beautiful ridge.

o Sound: Solid and crisp ("Clink!").

· Hairline Cracks (Damage):

o Shape: Usually very straight and "sharp," cutting across the natural flow of the texture.

o The Test: If a hair or bristle can slide into the gap, it’s a crack.

o Sound: A cracked shell sounds hollow or dull when clicked together.
