Natural wallpaper includes materials such as grasscloth, mica, and cork. What distinguishes natural wallpaper from other materials is that the physicality of its appearance adds dimensionality to the walls. Grasscloth has an organic appearance that gives any space a fresh look. Best used in dry, low-traffic areas, grasscloth material is truly one of a kind. Cork wallpaper has a highly textured appearance thanks to its cork slabs that have been laminated to a substrate. Mica wallpaper contains numerous small mica stones or chips adhered to a substrate.
