The theme of our school's basic courses is "Towels". The towel pattern design course is a cross-disciplinary aesthetic course that combines social and arts and humanities fields. It uses the community attractions "Cat on the Roof" and "Cat Elementary School" as the main axis of pattern design. Various dots are used as creative elements, and techniques such as graphic repetition, color contrast, and harmony are used to complete the towel pattern design. This course consists of three parts. The first part is a field visit to the community, using tablet technology to take photos and incorporate "cat" scenery into the lens as a theme for towel design. The second part introduces the artist Yayoi Kusama and her dot creation characteristics to teach students Understand the principles of beauty. The third part guides students to use dot stickers and buttons to complete the design of cat-themed towel patterns.
