A pop-up gallery can be an excellent way to show and sell your artwork. They allow flexibility, while not requiring a large commitment of time and money. By offering this opportunity to fellow artists, you will increase sales and can use them to help you run and promote the gallery. I detail what should be included in a proposal to a property owner and how to write a Call to Artists to attract other artists to join you. I also talk about the many events you can have at the gallery to attract more visitors.
