Bottom line is: you need first to work on how to become irresistible to the art fair audience, how to get their undivided attention, how to become relevant.
Can they get something similar at TJ Maxx or Pottery Barn? Whoops ... something missing here!
People need to understand what you are about, why does it matter to them and what is in it for them. Have any time for social media? Show off your new work on FB -- and how is that website?
If there are people at the art fair it isn't because they didn't have anything else to do (think Saturday afternoons in the fall in America ... college football comes to mind for me) and they are walking down Walnut Street or Westheimer or Meramec or State and glancing around ...
P.S. unless you missed John Baun and John Houle's discussion about this marketing last week, here it is again: http://www.artfairinsiders.com/profiles/blogs/apples-to-apples
