How did Claes Oldenburg make his sculptures?

Not all artists actually construct the pieces themselves. Early in his career, Oldenburg married Patricia Muschinski, who assisted him in many of his sculptures. There is considerable debate as to what role she played in the creation of his work. It is known she was an experienced seamstress and helped him the technical aspects of his soft sculptures, although for reasons that remain unclear, her name is never identified with his work. They later divorced. He is presently married to the art historian and critic, Coosje van Bruggen, who since 1985 has collaborated with Oldenburg on much of his work. Here is an article written by Oldenburg's first wife. She recounts how she started out hemming his trousers and later became the person that constructed his soft sculptures in the 60s.
