Folk art are the names we use for our own collective, and community-based experiences, and traditions like the kinds of food we eat during holidays or how we all know and understand proverbs because they come from our shared experiences. These arts endure because they name the shared experiences of many people.
"It is a way of distinguishing arts that represent more than an individual point of view. The term is also used because, in this country, the creative expressions of ordinary people are not always seen as art, or as significant, or as part of a tradition. Because mainstream and elite notions of art generally marginalize the majority of world cultural and artistic traditions, the notion of "folk" art is a way of making equal room for all peoples' habits of expression and creativity." ~ folkloreproject.org
