Erased Classic is a collection of carpets by Jan Kath. They are based on classical patterns from Italian wall coverings and Indian saris. The carpets are produced by weavers at manufacturing sites in Kathmandu. But their final look is caused by acid, which makes the patterns fade and disappear. The customer cannot only define the color, materials, size, knot density, and design, but also the degree of erosion.
