But back to the process: First an artist has to investigate to find suitable shows for their work. One such venue is to study Art Opportunities Monthly, a vetted listing of hundreds/thousands of opportunities. Each show typically has a theme the curators want to highlight.
Then an artist has to apply, sometimes paying a fee (usually around $35), submit digital images (usually), wait (usually 3-6 weeks) to hear whether the work is acceptable for that particular theme, then, if accepted, get any 2D piece(s) framed ($$). Many shows then take a percentage of the sale price if the work is sold.
Plus there are mandates that differ from show to show, quite outrageously one may think. For example, a recent show sent a checklist of 18 items that participating artists need to address; another has 6 full pages of instructions to follow. And those are local shows. It’s a wonder.
