Layer of bricks

MASON

Think of the skilled tradesperson who builds with bricks and mortar.

The clue "Layer of bricks" hints at someone who works with bricks rather than the bricks themselves. "Mason" is the term for a craftsman who builds or layers bricks, stone, or similar materials. The wordplay here is subtle—it plays on the idea of "layering" as an action done by the person, not the object. Think of a bricklayer or stonemason, and the answer clicks into place.
