Whipstitch refers to a simple stitch used in sewing, embroidery, and mending. The word is derived from the verb "whip," which means to sew rapidly and haphazardly. There are many synonymous words used to describe whipstitch, including overcast stitch, blanket stitch, and buttonhole stitch. Overcast stitch passes the thread over the edge of the fabric multiple times, providing a neat and secure hemline. Blanket stitch is similar to whipstitch and is used as an ornamental stitch on the edges of blankets and other fabric items. Buttonhole stitch is used mostly for buttonholes and loop closures, giving the impression of a decorative edge. No matter the name or application, whipstitch remains a versatile and practical technique used by sewers and craftsmen worldwide.
