A salai, also known as a needle, is a small pointy tool that helps people sew things together. It has a sharp end that can poke through fabric or other materials, and a loop at the other end where thread goes through. When people sew with a needle, they push it through the fabric, wrap the thread around it, and then pull it back out to create stitches that hold the fabric together. Salais come in different sizes and shapes, depending on what kind of sewing a person needs to do. Sometimes people even use really tiny salais to make really intricate stitches!
