FYI- NPR has a podcast by me. Google -One Artist's Secret To Success- Good data there.

The business of art matters. Talent in selling the art matters. Artists have to do outreach all year, out side of the traditional gallery and art festival system. I do a lot of direct mail.
Snail mail is personal, I draw on the letter and envelope. People get art from me  by snail mail.
Out marketing every other artist is a key to making sales.  I send snail mail art career updates all year. People need to brag about artists they know. Word of mouth matters. Artists need to consider self promotion.
