In Sewell's yard a purple plastic tricycle hangs from a tree. The toy is surrounded by bags of empty soda and beer cans, and is a statement about children’s health and safety. Like all other assemblages in her yard, and in the fields, and on her porch, this one changes forms regularly, prompted by Sewell’s intention that her creations continually evolve and respond to changes in her moods and attitudes. “I see things in a different manner,” she says. “A new definition come. I don’t want to see my yard in a constant way.”
