3.1.4: Texture
Texture is the surface character of a material which can be experienced through touch or the illusion of touch. Surface texture can work differently depending on the purpose of the object. Functional objects (pottery, furniture, jewelry, fabrics, glass) that are meant to be handled, worn, or sat on need to have textures that be safe and appealing for the user. Textures can also be purely visual. As a result, they can be anything from the actual texture of the materials that make up the piece to invented textures trying to imitate something else.
In two-dimensional works, there are actual textures; ones you can actually touch and feel, and implied texture, or visual memories.
