What exactly is Craft ???

Craft - Definition 

Although "craft" can't be defined, this is what I say about it.

A craft is a pastime or a profession that requires particular skills and knowledge of skilled work. In a historical sense, particularly as pertinent to the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods, or their maintenance, for example by tinkers. The traditional terms craftsman and craftswoman are nowadays often replaced by artisan and rarely by crafts person (craftspeople).The decorative arts are arts or crafts concerned with the design and manufacture of beautiful objects that are also functional. It includes interior design, but not usually architecture. The decorative arts are often categorized in opposition to the "fine arts", namely, painting,drawing, photography, and large-scale sculpture, which generally have no function other than to be seen.
