Lewis's practice works with found materials, including seashells and fabric scraps. Much of her work focuses on the experiences of the African diasporic community. She uses recycling because it is circular and has roots in her ancestry. Lewis's earlier work used materials such as “wood, scrap metal, cement, wire, plaster, stones, paint cans, chains and rebar, her latest work relaxes further into fabric.”[4] Using the globally sourced materials she creates a sense of community and ancestry in the work.Lewis's use of reclaimed scraps and materials connects with histories of resourcefulness and is environmentally conscious, which she tries to keep in their found states.
