An embroidery needle is a specialized sewing tool designed for hand embroidery. It features a slender shaft and a larger eye, allowing for easy threading of embroidery floss or specialty threads. The needle's sharp point helps it easily penetrate fabric, making it ideal for various embroidery techniques. Embroidery needles come in different sizes and types, such as crewel needles for fine threads and tapestry needles for thicker yarns. Choosing the right needle is essential for achieving the desired stitch quality and ensuring the fabric remains undamaged during the embroidery process.
