3D/2D's core activity is organising events that provide makers, designers, craftworkers and artists with venues where they can exhibit their work and sell directly to the public. The origins of the organisation go back to 1981 and the first fairs were held in Edinburgh in the Assembly Rooms. Fairs in Glasgow began in early 1983, with other towns and venues added later that year. Since then 3D/2D has established a strong, reliable reputation for quality and diversity with both the public and potential exhibitors. Currently all the events that 3D/2D organises, or participates in, are based in Scotland. 3D/2D's exhibitors are drawn from all over Britain, with the majority living and working in Scotland.
