Apartment Therapy Green Home points to Jenny Hurth who makes bags and a variety of other products from discarded vinyl signs or banners. Pictured above are her grocery totes and laundry hampers.
From the Jenny Hurth site:
Everything you see on this site has been designed & hand sewn in the San Francisco Bay Area from discarded vinyl signs and banners Originally printed for local trade shows, conventions, municipal or private advertising, these ENORMOUS banners would otherwise end up in the landfill. It is our goal to make beautiful and practical items out of what has been discarded.
