Lining fabric is a thin and lightweight material that is used to cover the inside of clothing, bags, and other textiles. It helps to protect the outer fabric and provides a smooth and comfortable surface against the skin. Lining fabric can be made from a variety of materials, including polyester, cotton, silk, and rayon, and is available in a range of colors and patterns to complement the outer fabric. It is typically sewn into the garment or item during construction and is not meant to be visible from the outside. Lining fabric is an essential component of many types of clothing and accessories.
