Kasthall's late Head of Design, Gunilla Lagerhem Ullberg, created a rug to show the endless possibilities of combining colors and patterns within a Kastall pattern family, Häggå. The no-name rug was placed on the front page of a Kasthall brochure that same year, thus the name. After the rug was shown, it has been woven in different color combinations over the years. So often, the rug has become a hallmark for Kasthall.
