Overlockers are incredibly versatile, offering various stitch types to accommodate different fabric types and garment needs. The most common stitches include the 3-thread overlock, which is ideal for lightweight fabrics, and the 4-thread overlock, perfect for medium-weight materials. Additionally, overlockers can perform rolled hems, gathering stitches, and even flatlock stitches, making them invaluable for both home sewers and professional tailors.
