Who and what are artisans? They're folks who take a particular pride in creating something by hand, often using traditional methods that have been supplanted by industrialization.

They sell them through the Internet, farmer's markets, gourmet shops and, sometimes, if they’re successful, their own storefronts or stalls in the establishments like the happening Union Market. Here are some local craftsmen and women whose delicacies are worth seeking out.
