Embroidery needles are specialized sewing tools designed for hand embroidery. They typically have a larger eye, allowing for easy threading of thicker embroidery threads or floss. The needle's sharp point helps it easily penetrate fabric, making it suitable for various embroidery techniques. These needles come in different sizes and types, each tailored for specific fabrics and thread types. For instance, crewel needles are used for wool threads, while tapestry needles have a blunt tip for working with canvas. Choosing the right needle is essential for achieving clean and precise embroidery results.
