An overlocked seam is a type of stitch used in sewing that finishes the edges of fabric to prevent fraying. This technique is commonly performed with a serger or overlock machine, which trims the fabric edges while simultaneously stitching them together. Overlocked seams are often found in knit fabrics, as they provide stretch and durability. These seams are popular in garment construction because they create a clean, professional finish. Overlocked seams can be used in various sewing projects, including clothing, home decor, and crafts. They are especially useful for items that require flexibility and strength, such as activewear and stretchy garments.
