An overlock machine, often called a serger, is a type of sewing machine that sews, cuts, and finishes seams simultaneously. It uses multiple threads to create a strong, durable seam that encloses the raw edge of the fabric, preventing fraying. This process is faster and more efficient than traditional sewing methods for certain applications.

Overlock machines typically have two to five threads. The most common setup uses four threads: two for the upper looper, one for the lower looper, and one for the needle. These threads interlock to form a secure stitch. Different stitch types can be achieved by adjusting the number of threads and the settings of the machine. Common stitches include the 4-thread overlock for durable seams, the 3-thread overlock for finishing edges, and rolled hems for delicate fabrics.

The primary advantage of an overlock machine is its speed and the professional finish it provides. It is widely used in the garment industry for constructing clothing, particularly knit fabrics, as well as for hemming, seaming, and decorative edge finishes. Home sewers also utilize overlock machines to achieve professional-looking results on their projects, enhancing the durability and appearance of handmade garments and home decor items. Learning to thread and operate an overlock machine can have a steeper learning curve than a standard sewing machine due to the multiple threads and tension adjustments involved.
