Advantages of Using the Union Lockstitch
A double needle sewing machine is a specialized sewing machine that uses two needles and two threads simultaneously to create parallel rows of stitching. It is equipped with a unique needle holder that holds both needles side by side, allowing for specific stitching techniques that single-needle machines cannot achieve. This machine can create various stitch types, including straight stitches, decorative stitches, and cover stitches, making it versatile for different sewing projects.
