- Lockstitch
A sewing machine is a mechanical or electronic device used to stitch fabric, leather, and other materials together with thread. It uses a needle to create stitches, while a feeding mechanism moves the material, and a bobbin provides the lower thread to lock the stitch. Powered by a motor, foot pedal, or treadle, sewing machines increase the speed, accuracy, and quality of stitching compared to manual sewing.
