What is Marquetry? Have you ever made a picture by cutting many pieces of paper or wood and putting them together? If so, you were following a process similar to marquetry. Marquetry is a process of creating patterns and designs on objects like furniture using thin veneers or layers of materials like hardwood, shell or ivory. Pieces are cut and fit together to form a very decorative flat surface image. Marquetry is an old process that dates back thousands of years. Ancient Egyptians practiced a similar process in which they made inlay surfaces, which means filling recessed areas with small pieces of material. But marquetry really developed into a sophisticated art form in Europe in the mid-1500s.
