Thangka is a traditional form of Tibetan art that features detailed and colorful depictions of Buddhist deities, religious symbols, and landscapes. Thangkas are typically painted on cotton or silk canvas, but can also be made with a mix of materials such as fabric, paper, and metal. Thangka embroidery is a variation of this art form that involves the use of needles and thread to create intricate designs and embellishments on a fabric background.
