Clay is incredibly versatile and relatively easy to work with, making it a great modeling material for beginners and expert sculptors alike. You should consider the feel, hardness, and texture of the material when making the very personal decision of the type of clay you'll use. You should also consider the equipment available to you when choosing the right clay for your goals. For example, whether you have access to a kiln will determine some clay products you can and can't use, as will the temperature you plan to fire.
