Fig. 544. Bars joined together.

Fig. [544] explains how the double bars are bound together by an ordinary double knot.

Single chain (fig. [545]).—This is made with two single threads, by knotting them alternately over each other, that is, each in turns serving as cord to the other.

Double chain (fig. [546]).—The double chain is made in the same manner as the single, only with a double thread.
