"So we [with Kate DiCamillo] decided to give the friends an object and see what they did with it. The object was a sock and it went from there. Once we got going, once we got on a roll, it became very easy to work together and to figure out how to do it. We would meet for two-hour segments, usually from 10-12, two or three times a week. We met all one summer, and I think into the fall."
