I have a 5-year BFA in studio art/ metalsmithing/ jewelry making, but it's very difficult to make a living at it. This doesn't mean impossible, but you need to go into it knowing that it may take a while and a good deal of financial investment. That's why my income is from beadwork, not what I studied in college.

Craft stores will not offer classes in metalsmithing. That's why I suggested JC's and Continuing Ed.
