The applications of high-speed single needle lockstitch sewing machines are extensive. They are primarily used in the apparel industry for sewing various types of garments, including shirts, dresses, trousers, and jackets. Beyond clothing, these machines also find utility in industries such as upholstery and automotive, where they are employed to sew heavier materials like leather and canvas. Their adaptability makes them suitable for both mass production and specialized projects, catering to the diverse needs of manufacturers.

Not all leather projects require the same thickness of thread. Factors such as leather thickness, the type of stitch, and the intended use of the item play a significant role in determining the appropriate thread size. General recommendations suggest using heavier threads, typically around size 69 to 138, for thick leather like harness and luggage leather, while finer threads serve well for lighter-weight projects.
