After reading hundreds of blogs/articles concerning whether artists should try to get their work into galleries, I have come to the following conclusions:
1. Don't even try it if you're scheduled to do a lot of shows. How can a gallery charge 2 to 3 times your direct sales price when so many customers are paying so much less?
2. Don't do it if you still want to do art fairs and festivals. See #1
3. Don't do it if you don't feel "ready" to talk the talk, don't want to act smug and holier than thou, or wait months between sales.
4. In short--you must decide what kind of artist you want to be. I believe the universe will let you know when the time is right to make the big leap. It may never come--I say, who cares?
