The purpose of this course is to create a class uniform that represents the common atmosphere of the class, so that students can learn about common indigo dyeing plants, indigo dyeing handicrafts and products, the indigo dyeing production process, and the techniques of making various indigo dyeing renderings. This course combines bilingual art and craft, extending from visual beauty to life and natural technology, cross-domain communication between nature and art, and then returning from cultural and subject exploration to the life application of artistic creation.
