Art is a form of expression and it includes a wide range of forms and types. Craft is more defined in a specific type of supply used to produce it. I've seen many crafts that are definitely works of art. "Craftsmen" often train for years. Mosaic tile and stained glass are examples of crafts that certainly can turn out to be masterpieces of art.
I think anybody can call himself/herself an artist if he/she practices the skill and creates pieces from the heart.

The difference between art and crafts is quite clear. Crafts are things that we " re- create " alegoric to our culture or folcklre. Its a memoir of our cultural folcklore. In art you don"t re- create, rather, you are creating. The designs you do on your gourds is creation,therefore, art. This is something that was in you and you find a way to express it. These expresions of your inner thoughts or desires are unique in every artist.When a craftman builds something he is expressing the collective memoir of his culture and folcklore.

I just finished an art show that included over 200 artist from around the country. Some great work was shown, to include painting, woodwork, sculpture, drawing, jewelry, glass work and pottery. One booth had pot holders. Sorry, but it just did not fit. Many of the artists that have done this show for years, were appalled and are not going to participate next year. The pot holders were nice, but I'm sorry. They did not belong there. Even some of the attendees that frequent this show every year thought it brought the quality of the show down.
