Traditional Islamic paper from North India made from sunn hemp fibre. Handmade on a chapri, a grass stem screen. Sheets are dried on a plaster wall and surface sized with wheat starch. The colour is applied by brush. Indigo plant dye is the probably the oldest of all dyes and was named indikon by the Greeks in reference to its Indian origin. After colouring the paper is burnished by rubbing on a curved block of wood with a smooth stone.
