All kinds of brocade paper and silk are used to frame, beautify or protect ancient and modern paper and silk paintings. Paintings and calligraphy made on rice paper and silk are often wrinkled and fragile due to the colloidal effect of ink color, which is not convenient for viewing, circulation and collection. Only by mounting the painting heart to make it flat, and then matching it with corresponding silk according to its color shade, composition complexity and frame width, can we mount it into various forms of frames, which will enrich the pen and ink and color and increase the artistry of the works.
