The Bittern was the winning design from Graham & Brown's association with Central St. Martin's college in London. Meeting an eco-based brief, Jo Angell designed a wallpaper inspired, by the Bittern, a bird that lives in reed beds. Only 50 pairs remain, and with rising sea levels due to global warming they are under threat. All of the papers in Graham & Brown's eco collection are printed with water-based, VOC free inks, on FSC acredited, sustainable paper. The wallpapers are also wrapped in a compostable material, making it the most eco-friendly wallpaper available.
