Develop a theme. The theme should be flexible and open-ended enough to encompass a variety of artworks in different media.
Choose a title for the exhibition. The title should be directly related to your theme, so that it clearly reveals what the exhibition is about.
Find artists who have done work based on this theme. You might also consider asking an artist whose work you like to create something new around this theme.
Invite the artists to participate in the exhibition. Many artists now have websites with readily available contact information. For other artists, however, you may need to contact their galleries first to ask permission to use their art in your exhibition.
Write a press release. This is your chance to explain the title and theme of your exhibition to the press, as well as name which artists will be featured in the show. The press release should be no longer than one page.
Install the artwork in the gallery. When possible, you should ask the artists for their input on the installation and placement of works of art. This does not mean you always have to take their advice, but you should always listen and consider their feedback.
