Many traditional crafts, such as ironworking and glass-making, have been elevated to the fine or applied arts and taught in art schools; or they have been repurposed as folk art, characterized as objects whose decorative form supersedes their utilitarian needs. Folk art is found in hex signs on Pennsylvania Dutch barns, tin man sculptures made by metalworkers, front yard Christmas displays, decorated school lockers, carved gun stocks, and tattoos. "Words such as naive, self-taught, and individualistic are used to describe these objects, and the exceptional rather than the representative creation is featured." This is in contrast to the understanding of folklore artifacts that are nurtured and passed along within a community.
