El Warcha, a multidisciplinary participatory design collective founded by Benjamin Perrot, champions collaborative, street-facing workshops that involve local residents in the creative process. The group produces temporary urban furniture, public installations and events that foreground practical education and civic engagement. For this week of open workshops, textile practice is central: participants will draw, draft patterns and sew together to co-create a large collective textile installation that will transform the space and explore community, materiality and shared craftsmanship.
