It is now too late to register an exhibition for May 2020. You will be able to register for May 2021 in September.
First, register as an Artweeks member (as an individual or as an organisation).
Then, to enter an exhibition you will need your contact and venue details (including dates and times), a strong image (preferably square) for the printed festival guide, an accompanying 12-15 word description and a short paragraph to accompany the on-line listing.
Once you are a registered Artweeks member, you should upload a biography, an image of yourself/an artist at work and six images for your free on-line gallery.
