Not long after she left the Slade in the 1960s, I invited Phyllida Barlow to present a week-long introductory sculpture project to a group of students at Camberwell School of Art in London.
She asked that the project studio be cleared of furniture, equipment and materials, except for a large stack of flat-packed cardboard boxes in the middle of the empty space. Confronted with a long rectangular room, with a door at one end and a high cube of stacked cardboard in the middle, the students spent five days filling the space with a great variety of invented box structures, with each new one gradually blocking the view of their earlier efforts.
