1. Versatile Stitching Options Dual needle sewing machines can produce a variety of stitch types, including straight stitches, zigzag stitches, and decorative stitches. The ability to create multiple lines of stitching opens up new creative possibilities for garment finishing, quilting, and crafting projects.
Overall, heavy duty sewing machines are built for longevity, with all-metal construction and premium internal components. They can sew for years without issues and only need periodic oiling. By contrast, plastic gears and components in standard machines wear out more quickly. Professional heavy usage requires the durable construction of true heavy duty machines.
The double needle stretch stitch utilizes two needles and a single thread from the spool, creating two parallel rows of stitching on the top side of the fabric. Meanwhile, the bottom side features a zigzag stitch that allows for stretch, ensuring that the seams maintain their integrity and do not break when the fabric is pulled or stretched. This unique combination of stitches makes it ideal for fabrics that require flexibility, as it allows for the functional benefits of a stretch stitch without sacrificing the aesthetic appeal of a straight stitch.
