The 5 Ways project would serve as an excellent teaching resource for design educators, to introduce their design students to the capacity for transformative design:
"5 Ways is a project by Becky Earley and Kate Fletcher made up of five inter-connected approaches to fashion textile design. It brings together creativity and ecological thinking in fabric form and offers a range of starting points for understanding more about what ecological qualities such as diversity, participation and efficiency might mean for fashion textiles." (5 Ways)
Familarize yourself with the project, and the site, and encourange your design students to think creatively in this context; as designers, the project will surely inspire your students.
