Key4Life helps former offenders of knife crime to rehabilitate and live a life without crime and violence. Our interactive campaign "Stencil Storie" aims to rethink the knife as a constructive tool. Programm attendees of Key4Life express what made them change their lives with the help of self-made stencil artworks. Typographic workshops introduce them to creative ways of sharing feelings and reoccupying public space. The campaign amplifies their voices – right in the streets, where a mentor's advice is most needed. In collaboration with city councils and local communities, urban gathering places are our canvas. Viewed from the top, the installations work as motifs for posters.
