Interest in outsider art has been gathering momentum in the last decade. The Museum of Everything and the Whitechapel Gallery’s Inner Worlds Outside exhibition saw self-taught artists and craftspeople join recognised names in the limelight. Now Tate Britain takes on this previously overlooked genre in its first major survey of British Folk Art. With the aim of elevating craft from its social history function, the show is part of an ongoing blurring of boundaries between art, craft and design. A Crimean pincushion and a set of carousel horses are among an extensive range of works on display.
