The German manufacturer Architects Paper presents an extraordinary wallpaper at the 100%Design in London this year. A thin layer of stone material is applied on cotton weave. Depending on the sort of stone the layer is either made of stone powder or – and this is really sophisticated – a thin layer of the natural surface of the stone is transmitted through a chemical process directly on the backing textile. Due to naturally occurring rock formations within the structure and colours, each drop has the property of being slightly different which offers no reason for complaint. Each drop is unique.
