Wentworth uses common and utilitarian objects in his sculptures in a way that can be both witty and unsettling. He has observed 'humour is trying to find pockets of breathable air in a stifling atmosphere'. Wentworth gave up making sculpture for a while in the 1970s, thinking that it had become 'as dry as broken biscuits'. He emphasised the difficulties in making sculpture when saying 'I hate the way I work, the anxiety in waiting for enthusiasm to meet method, material to meet image, idea to meet language'. As an inveterate collector of discarded objects, Wentworth regards their presence in his studio as enabling him to create an imaginative order rather than one which is typecast.
