3. Fabric Compatibility These machines can handle a wide range of fabrics, from lightweight materials like silk to heavier fabrics like denim and canvas. This makes them an excellent choice for various sewing projects, whether you're working on clothing, home décor, or accessories.

An overlock machine, often referred to as a serger, is a specialized sewing machine designed to create seam finishes and provide a clean, professional look to garments. Unlike conventional sewing machines, overlock machines can sew and trim fabric edges simultaneously, preventing fraying and ensuring durability. They are widely used in the apparel industry for hems, cuffs, and seams, especially in knit fabrics.

1. Select the Right Double Needle Choose a double needle that suits your project. The needle size (e.g., 80/12 or 90/14) and the distance between the needle points will affect your stitching. A 2-3mm spacing is standard for most uses.

Moreover, the walking foot mechanism helps to feed all layers of fabric evenly, which is crucial when sewing thicker materials. This ability reduces the risk of uneven seams and ensures a professional appearance in the final product.
