Background technique

Fine art refers to the art that occupies a certain plane or space and has a visual image for appreciation. According to the purpose, it can be divided into two categories, namely pure fine arts and arts and crafts. It uses certain material materials, such as color, paper, canvas, soil, stone, wood, metal, etc., to shape a visible plane or three-dimensional visual image, to reflect nature and social life, and to express the artist's ideas and feelings. art activity. Among them, painting is an important category of fine arts. There are art painting courses in elementary schools and junior high schools. Painting requires some specific painting tools, and the drawing board is one of the indispensable tools. Generally, the drawing paper is fixed on the drawing board, and then the drawing board is fixed on the bracket, which can be erected.
