Under “My Catalogs” start a new one. You choose a visible name (for example “Paintings 2020–2026”) and a short description that sets context for the set.
You can mark the catalog as public: it will be reviewed before appearing in the showcase and must meet the minimum number of active artworks shown in the form.
After saving, the catalog appears in your list; open it to manage artworks and, under edit, upload a catalog logo if you need one.
Wireframe: main fields of the new catalog form and the public checkbox.
