A blind needle is a type of needle with a dull tip that is commonly used for sewing or fabric work. It is not sharp because it is used to join layers of fabric rather than piercing or sewing the fabric. Blind needles are typically used to secure fabric edges or layers, making the sewing process easier. They are especially used in sewing projects to keep the fabric in place and prevent it from slipping during stitching. The heads of blind needles are usually colored, making it easy to distinguish between different sizes and types. Blind needles are a fundamental tool commonly used in sewing, fabric work, and handicraft projects.
