What technique does a whip stitch employ?

The whip stitch is a hand-sewing technique primarily used to join two pieces of fabric together. This stitch is characterized by its simple, quick method of securing the edge of one piece of fabric to another, making it a popular choice for hemming or finishing edges. The stitch is executed by passing the needle through the fabric at an angle and weaving it in and out along the edge, which creates a series of small stitches that are visible on one side but often remain nearly hidden on the other, contributing to a clean finish. This technique is especially valued in stagecraft for its ability to produce durable seams for costumes or fabric props while allowing for flexibility and ease of alteration when needed.
