A sewing needle is a slender tool used for stitching fabric or other materials together. It typically has a pointed end for piercing the material and a small hole, called an eye, near the pointed end to hold the thread. Sewing needles come in various sizes and types, designed for different fabrics and sewing techniques. Sewing needles can be made from various materials, including stainless steel and nickel-plated steel, to ensure durability. They are essential tools in the craft of sewing, which can be used for making clothing, home decor, and other textile projects.
