knopfverband

Knopfverband, also known as buttonhole stitch or blanket stitch, is a type of embroidery and sewing stitch used for a variety of purposes. It is characterized by a series of looped stitches that form a decorative edge or are used for joining fabric pieces. The stitch is created by passing the needle through the fabric, then looping the thread around the needle before re-entering the fabric a short distance away. This looping action creates a visible knot or button at the edge of the stitch.

Historically, the knopfverband has been used in traditional embroidery for decorative edging on garments, linens, and tapestries. Its robust nature also made it suitable for reinforcing edges and preventing fraying, especially in heavier fabrics. In sewing, it can be used for finishing raw edges, creating decorative appliqué, or as a functional seam where strength and a decorative appearance are desired. The spacing and tension of the stitches can be adjusted to create different visual effects, from tightly packed, almost solid lines to more open, lacy patterns. Modern applications include both handcraft and machine embroidery, where it can be used to create intricate designs or to add a professional finish to fabric projects. The term "knopfverband" itself is German, translating literally to "button connection" or "button binding," reflecting its knot-like appearance and its function in joining or securing.
