The ecorative arts are traditionally defined as ornamental and functional works in ceramic, wood, glass, metal, or textile. The field includes ceramics, furniture, furnishings, interior design, and architecture. The decorative arts are often categorized in opposition to the "fine arts", namely, painting, drawing, photography, and large-scale sculpture. Some distinguish between decorative and fine art based on functionality, intended purpose, importance, status as a unique creation, or single-artist production. Decorative arts, or furnishings, may be fixed (for example, wallpaper), or moveable (for example, lamps).
