Buttonhole stitches are very versatile, as it is the most appropriate stitch for sewing buttonholes and one can also use them to edge fabric instead of doing a Hemstitch finish. Buttonhole stitch is also known as blanket stitch because it was often used as an edging on blankets. The stitch is also used for mirror studding. Buttonhole can be both decorative and practical that can be varied to form pyramid shapes, or can be whipped or threaded with a contrasting color.

This stitch is worked from left to right over two imaginary lines. Bring the thread out on the lower line, insert the needle in position in the upper line making a straight downward motion and then loop the thread under the needle point. Pull the needle through the fabric to form a loop and repeat this process along the line.
