A journey through the world of sustainable clothing with Bo and Indy. At the request of the organization of the Dutch Sustainable Fashion Week, I developed a lesson for 8th-grade students. It is an interactive lesson that can be taught by teachers using a teacher's guide. By involving experts in the development process and regularly testing with the target group, we have created a great final product that takes into account the interests and experiences of the students. By emphasizing the importance of sustainability and integrating diversity, it has become a fun and educational lesson, according to both teachers and 8th-grade students.
