Sling sewing machine

A Brief History

When threading a double needle, one must thread two spools of thread, which are placed on the machine concurrently. This setup may require additional adjustments in the tension settings to ensure even stitching. It's also crucial to use a walking foot or a dual feed feature on the sewing machine for the best results, as this helps manage the fabric layers effectively, particularly when working with heavier or slippery fabrics.

- Walking Foot Mechanism A walking foot is essential for sewing multiple layers of leather, as it helps maintain even tension across the fabric. This feature can prevent puckering and ensure a smooth finish.
