A one-page Czech encyclopedia entry on Holbein technique (Holbeinstich), a double-running line stitch used in counted-thread embroidery on evenweave fabric. It explains how the stitch is worked in two passes to make a continuous line, how branching motifs and thread ends are handled, and the related boxed stitch variant. Four numbered diagrams (figs. 1741-1744) illustrate the stitch, and the entry cites pattern sources by Emilie Bach and Thérèse de Dillmont.
