Leather Brush is a genre of folk art that is a style of painting developed by letter arts. It is a beautiful, often whimsical, writing style called "Flower letter" or "Rainbow letter". The name refers to the type of brush made of leather material that is used rather than a traditional brush. Using watercolor, the leather brush is used to create vibrant artwork, usually with letters or words incorporated into the work.
In the East, there is a traditional belief that leather brush art brings good luck to the home, driving away bad luck and protecting health. Recently, many people's preferred text includes phrases describing parents’ love for their children, respect for others and friendship.
Danny Ryoo explains, "Growing children's minds are sponges that absorb life's experience. If you hang a piece of leather brush art that includes the children's name at home, the children will feel proud of their names. Through this, children are able to learn about the love, understanding and harmony from families".
