A hemmed square of a thin cloth is known as a hankie, also called a handkerchief. It is a form of kerchief basically made of thin fabric. Sometimes it is also used as a decorative accessory in a suit pocket, known as Pocket Square. Handkerchiefs are made from different types of materials such as cotton, silk, linen, and synthetic fabric. A plain piece of cotton turned into a stylish, decorative accessory. The handkerchiefs are embellished with silk laces and embroideries. The art of decorating fabric or other materials with needles and thread or yarn is known as embroidery.

It may also incorporate different materials such as pearls, beads, quills, and sequins. The primary stitching tool in embroidery is the needle, which is available in various sizes and types. The base material of the fabric is varying from place to place. Silk, wool, and linen have been in use for many years for both fabric and yarn. Though machine embroidery is also available yet, traditional hand embroidery is much more popular. Traditional folk techniques were passed from generation to generation. Ms. Sunanda is an artist who is an expert in handkerchief embroidery. She is from Goa, a state in India.
