Holbein stitch

Holbein stitch is a simple, reversible line embroidery stitch most commonly used in Blackwork embroidery and Assisi embroidery. The stitch is named after Hans Holbein the Younger (1497-1543), a 16th-century portrait painter best known for his paintings of Henry VIII and his children, almost all of whom are depicted wearing clothing decorated with blackwork embroidery.
