Artists always need supplies to do their work. They acquire the necessary items in specialty stores or art and craft shops. Painters will get oil paints, brushes and canvas through local suppliers. Leather workers may find punching tools. Sculptors generally must order their stone directly from quarries, but this is an exception to finding readily available art supplies locally. Many people who wish to learn how to produce art will inquire at an art and craft store about classes. Many of these shops and small stores have information and provide their own classes. Local artists generally teach these classes to encourage new artists and make a bit of money when their sales are slow.
