At the heart of the Union Lockstitch is its unique mechanism, which utilizes two threads—one from the needle and the other from a bobbin underneath the sewing plate. This lockstitch design creates a strong, durable seam that is essential for various types of fabric, including heavy materials like denim and lightweight textiles like silk. The machine operates by interlocking these two threads through a series of movement cycles, ensuring that the stitches are evenly spaced and consistent in tension.

Materials You’ll Need

A specialized zigzag presser foot typically features a wide groove at the bottom. This groove allows the needle to move freely from side to side without obstruction when creating the zigzag pattern. Additionally, many zigzag presser feet have markings that guide seam allowances, making it easier for users to achieve precise stitching.

Moreover, the built-in walking foot saves time and enhances convenience. Traditionally, sewing enthusiasts would have to pause their work to switch between different presser feet depending on the fabric type. With a sewing machine equipped with a built-in walking foot, users can transition smoothly between fabric types without interrupting their workflow. This feature encourages creativity and experimentation, as sewists can confidently tackle a wider range of projects without the fear of poor results.

1. Motor Power A stronger motor provides the necessary torque to handle thick materials. Machines with a powerful motor can sew through multiple layers of fabric without skipping stitches or causing jams.
