What stitch is commonly used to finish raw edges of fabric?

The zigzag stitch is a versatile sewing technique often employed to finish raw edges of fabric. This stitch creates a zigzag pattern along the edge of the material, which helps prevent fraying and unraveling. The stretchiness of the stitch allows it to accommodate movements in fabric, making it suitable for knit and woven fabrics alike.

Using a zigzag stitch is particularly effective when a serger or overlock machine is not available. It provides a quick and straightforward method for securing the fabric's edges, enhancing durability and providing a clean finish.

Other options may serve specific purposes, but they do not align as closely with the primary intention of finishing raw edges. For example, a straight stitch is typically used for seams rather than edge finishing, and while the blind hem stitch is designed for hems, it would not adequately secure raw edges. Similarly, an overlock stitch, although highly effective for finishing edges, is specifically associated with serging, distinct from the zigzag approach available on a standard sewing machine.
