Fast fashion project

Hi everyone! I’m working on a GS project relating to the problems of overconsumption of fast fashion. I’ve made awareness videos relating to this and presentations. My idea with this project is to get people to be more aware of the problems associated with fast fashion and encourage them to make more ethics decisions. I was thinking of holding workshops for children to teach them sewing (so they don’t throw out old clothes unnecessarily).This project needs to be sustainable so I was considering doing a clothes swap in my town. Any ideas and suggestions for sustainability nablilty or just for the project generally of how I can bring more awareness and make change?
