A "gulha" is a traditional type of needle used in the craft of embroidery. It is typically made of metal and features a sharp point and a small eye for threading. Gulhas are essential tools for artisans who create intricate designs on fabric, often using colorful threads. In many cultures, particularly in South Asia, gulhas are used in various forms of needlework, including kantha and zardozi. The size and shape of a gulha can vary depending on the specific embroidery technique, making it a versatile tool for both beginners and experienced crafters.
