Flat double knots with half knots (fig. [529]).—These are double knots followed by a third knot, or more correctly speaking, a half one of the first flat knots.

Collecting knots (fig. [530]).—As explained in fig. [525], these are flat double knots, made over more than two threads. The engraving shows, in the first place on the left, a flat double knot made over two threads, completed, and the first crossing of the thread for the collecting knot; secondly, the second crossing of the threads; thirdly how the collecting knot can, if necessary, be continued over 4 threads, and fourthly, how the collecting knot should be made to finish with a flat double knot.
Plaited and waved knots (fig. [531]).—Plaited knots are formed by a continuous repetition of the first crossing of the threads for making a flat knot, detail a; waved knots by a slight twist given to the plaited knots from left to right, detail b. These plaits of waved knots are secured by joining together the threads of opposite meshes, two and two, by a flat double knot.

Single crossed knots and double crossed knots (figs. [532] and [533]).—Two plain crossings of the threads, detail a, to begin with; after which you rapidly reverse the threads, turning the knot to the wrong side, drawing it up tightly at the same time; this forms the first knot, detail b. The second knot, fig. [533], is formed by 3 crossings, detail a; reverse the threads rapidly, to form the double crossed knot, detail b. For the following knots tie the threads together, as for the flat double knot, detail c.
