Birds have colorful feathers and a detailed body, so making paper birds is an extremely complicated process. Different body parts require different techniques and characteristics of the paper, and the feathers also have different shapes and colors. The basic body endoderm of birds is shaped by newspaper. Feathers are made of another special type of paper which, according to the feather characteristics of the birds, are cut to the corresponding shape, and colored naturally. The feathers are then superimposed on the surface of the basic endoderm. A fluffy, three-dimensional, lifelike paper art bird is completed.
