A subset of lampas, beiderwand uses one warp, which is divided into ground warp and secondary warp. The cloth itself is patterned and contains areas of two layer double weave, integrated double weave and ground weave. Woven predominantly in Schleswig-Holstein, beiderwand actually means both sides, as the back looks quite different from the front. Lampas is a more complex form of beiderwand and has been used extensively through early patterned cloth. Just think of the courtly silk dresses from the 1700-1800's.
