What is needle?

A needle is a long, thin, pointed tool used for sewing or suturing fabric, leather or other materials. Needles are typically made of stainless steel or other metals and are designed to be sharp enough to penetrate materials easily without causing damage. They can be straight or curved, depending on their intended use. Needles are commonly used in a variety of applications such as sewing, embroidery, quilting, knitting, crocheting, and medical procedures. Needles are also used in various crafting projects such as beading and cross-stitching. The size of a needle can range from small, fine needles for delicate fabrics to large, heavy-duty needles for thicker materials. The length and thickness of a needle are also determined by its intended use. Needles are important tools that have been used for centuries and continue to be an essential part of everyday life.
