Wicker is a type of weaving material made from natural fibers such as RATTAN, OSIER, and willow. The term 'wicker' is derived from the Old English word 'wicce, ' which means to bend or plait. OSIER is a type of willow tree with long, flexible branches that are often used for basket-weaving. RATTAN is a type of climbing palm tree with a strong, flexible stem that is often used to make furniture. QUARREL is a type of wickerwork that is made by weaving thin strips of wood together in a lattice pattern. All of these materials are commonly used to make wicker furniture, baskets, and other decorative items.
