I like to wear a silk neckerchief with a wool shirt in the winter. Using a slide, I adjust the neckerchief from tight around my neck in the cold morning to loose as the day warms up. A herringbone knot makes an attractive slide that facilitates adjusting a neckerchief's fit. In the following instructions, a herringbone knot slide is produced by interweaving two six-bight, seven-part Turk's head knots over a plastic tubing base.

Leather lace: 54" X 1/8" wide. (Or 27" of two colors)

Mandrel: 6" of 5/8" diameter dowel.

Base for the knot: 5/8" length of 7/8"OD/5/8"ID plastic tubing.

A fid; a lacing needle; saddle dressing and saddle soap.

Slide the plastic tubing onto the mandrel so that about 1/4" of dowel extends above the end of the tubing. The tubing will form the base for the neckerchief slide and will be covered by an interwoven herringbone knot.

Attach the lacing needle to the end of the lace to be used in the base knot and coat the lace lightly with saddle dressing.

To begin tying the base knot, a six-bight, seven-part Turk's head, hold the mandrel in your left hand with the tubing up, and grasp the end of the lace with the left thumb against the dowel just below the tubing.

1. Pass the lace up on the left side of the tubing so that it rests on the tubing's top edge in the back. Continue down the right side, cross over the starting end (that is, down and OVER 1), and make a bight (loop) under the bottom edge of the tubing to the left of the starting end. Adjust your thumb to secure this bight as well as the starting end. (If you are left handed, reverse "left" and "right" in these instructions, and you will produce the mirror image of the knot described here.)
2. Passing up on the left, cross OVER 1, make a bight at the top (above the top edge of the tubing), and pass down the right side to the front passing UNDER 1 (the starting end) and OVER 1 (the first bight) at the bottom and making a second bight.
3. Going up in the back, pass UNDER 1 and OVER 1 at the top. Down in front, pass OVER 1, UNDER 1, and OVER 1 completing the third bight.
4. The sequence continues going up, OVER 1, UNDER 1, and OVER 1, making the third bight at the top. Going down, pass UNDER 1, OVER 1, UNDER 1, and OVER 1.
5. Going up, UNDER 1, OVER 1, UNDER 1, and OVER 1; and down OVER 1, UNDER 1, OVER 1, UNDER 1, and OVER 1.
6. Going up, OVER 1, UNDER 1, OVER 1, UNDER 1, and OVER 1; and going down, pass UNDER 1 (the next bight at the top), OVER 1, UNDER 1, OVER 1, UNDER 1, and OVER 1 at the bottom. This completes the 6X7 Turk's head. (If a second color is desired, tuck the end under the next cross and continue with the second color.)
7. To begin interweaving the second Turk's head, start the pass up UNDER 2 (a crossed pair at the bottom one of which is the starting end), OVER 1, UNDER 1, OVER 1, UNDER 1 OVER 1 and UNDER 2 (which cross at the top). Going down, OVER 1, UNDER 1, OVER 1, UNDER 1, OVER 1 (the starting end) and UNDER 3 (one single and a pair which cross at the bottom).
8. Going up, pass OVER 1, UNDER 1, OVER 1, UNDER 1, OVER 1 and UNDER 3 at the top. Going down, pass OVER 1, UNDER 1, OVER 1, UNDER 1, OVER 2 and UNDER 3 at the bottom.
9. Going up, pass OVER 1, UNDER 1, OVER 1, UNDER 1, OVER 2 and UNDER 3 at the top. Going down, pass OVER 1, UNDER 1, OVER 1, UNDER 2, OVER 2 and UNDER 3 at the bottom.
10. Going up, pass OVER 1, UNDER 1, OVER 1, UNDER 2, OVER 2 and UNDER 3 at the top. Going down, pass OVER 1, UNDER 1, OVER 2, UNDER 2, OVER 2 and UNDER 3 at the bottom.
11. Going up, pass OVER 1, UNDER 1, OVER 2, UNDER 2, OVER 2 and UNDER 3 at the top. Going down pass OVER 1, UNDER 2, OVER 2, UNDER 2, OVER 2 and UNDER 3 at the bottom.
12. Going up OVER 1, UNDER 2, OVER 2, UNDER 2, OVER 2 and UNDER 3 at the top. Going down, pass OVER 2, UNDER 2, OVER 2, UNDER 2, OVER 2 and UNDER 4. This completes the interwoven herringbone knot.
