Nippon wallpaper collection is Sandberg's interpretation of the Japanese wabi-sabi tradition. It is a tribute to the belief in the beauty of the natural pure and imperfect. With humbleness to the large amount of diligent work and immense precision put in the making of traditional crafts and creations, gardens and ceremonies. The patterns were born in the memories of a journey through Japan, its cities, villages and scenery. All twelve patterns have first been hand drawn, created and produced with inspiration from traditional Japanese techniques.
