Begin with the use, not the finish sample
A material may look beautiful on its own and still be wrong for the place where it is proposed. Before choosing, we ask what it will touch, how often it will be used, what care it requires and how it meets the materials beside it.
That might mean choosing a tabletop finish for the way a family actually eats, thinking through a curtain's weight and movement, or selecting a piece of hardware because it is comfortable in the hand and appropriate for the conditions of the room.
The aim is never to use the most materials. It is to choose the ones that earn their place.
