In the Qing dynasty, indigo dyeing made Sanxia a major center of the dyeing and textile industries in northern Taiwan. However, complicated techniques have restrained development and innovation in indigo dyeing craftsmanship, and a lack of investment by younger designers has caused development to stagnate. The hypothesis behind this study was that cross-border cocreation is a potential method of breaking through this deadlock. Therefore, this study explored how the indigo dyeing industry could be revived through visits, observation, discussion, question identification, interviews with experts, and establishing connections among students of different ages in different schools, with their feedback to be used as study material for discussion with experts. The results from roundtables, spontaneous cross-border participation, and cocreation workshops indicated the possibility of reviving and innovating traditional craftsmanship. The results of this study could serve as a reference for (1) recreating the characteristics of indigo dyeing craftsmanship, (2) facilitating value-added regeneration of local industries, (3) reviving traditional craftsmanship, (4) providing university teachers and students with opportunities to transcend departmental and school boundaries, and (5) incorporating participation experiences into co-learning and cocreation to develop educational innovations for industry, the government, and academia in order to promote co-learning and cocreation among cross-border talent.
