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 hole, or eye, at the opposite end to hold the thread. Sewing needles come in various sizes and types, designed for different fabrics and sewing techniques. There are several categories of sewing needles, including hand sewing needles, machine needles, and embroidery needles. Each type serves a specific purpose, such as quilting or knitting. Proper needle selection is essential for achieving the best results in sewing projects.
