Sculpture is an artwork distinguished by its three-dimensional surface and form. Materials can be removed or added to create a three dimensional piece. Many materials use both these methods for instance, clay can be carved and added to, wood can be carved with additional areas glued or joined to different materials.. Metals can also be ground, welded, cast or bent into forms using tools. Sculptures can be small or large and only limited by the structural strength of their materials. I enjoy using natural materials and/or clay to create sculptural pieces..
