The not for profit social enterprise, is the brainchild of ‘entrepreneurial vagabonds’ Lachlan McWilliam and Lucie Galt. While traveling in Zimbabwe the pair discovered a business that produces copper and zinc wristbands, believed to have empowering and healing properties. The idea was to give each band a unique ID so that owners can pass them on and follow their progress along a global chain of hope. The exhibition will feature a Tree4Hope installation made from 13,000 hope tags collected at British festivals, with visitors invited to add their own messages of hope to the growing tree.
