Even if you don't want to, the idea is valid enough for you to make the effort in order to grow. It's easy not to show and not participate but than you leave many doors closed. I have been selling my work since 1998. I have been showing my work since 2004. My sales are higher because people talk and people want to "meet the artist" . If i can't be there, I at least make arrangements to have my work hung, and always make a point to include a price sheet and bio, so art connoisseurs have a way of reaching me. So if you want to sell your work, you have to display it. This isn't a gallery it's a wall in the middle of a town.
