Katan Banarasi silk is a handloom fabric from Varanasi (Banaras) made from pure silk threads that are twisted together to create a strong, soft, and lustrous fabric. The Katan technique is a plain weave that twists two warp and two weft silk threads, strengthening the material while maintaining its luxurious feel. These beautiful fabrics are the foundation for the renowned Banarasi silk sarees, known for their intricate designs, use of gold and silver zari work, and suitability for special occasions like weddings.
