Inlaid furniture decoration is a type of decorative art that involves inserting pieces of contrasting materials into the surface of a piece of furniture. Two common techniques used in this type of decoration are buhl and boule. Buhl is a technique that involves cutting thin pieces of wood, ivory, or metal and then inlaying them into the surface of the furniture. Boule is a technique that involves using small pieces of colored glass, stone, or metal to create intricate patterns. Both techniques can be used to create beautiful and unique pieces of furniture.
