- Vertical Double Half Hitch. Going left to right.
For training Vertical DHH we shall need one longer cord (approx 30 inches or 70 cm long) and several shorter cords (approx 15 inches or 40 cm long). Mount one of the shorter cords on the board using SL (Lesson 1). It will form the AC for the mounting row. Mount the rest of shorter cords on the AC with simple Larks Head knot (Lesson 2 (1)). Make a knot on one end of the longer cord and pin it to the board to the left of your work.
Please note, that when doing vertical DHH we have onle one WC (which moves horisontaly from left to right and from right to left) and multiple AC, which we use one after another. Vertical DHHs are called vertical because their ACs are vertical.
Your WC should be always under the AC before you tie the vertical DHH. Take the first AC from the left with your left hand and hold it under tension pulling down strictly vertical. Take the WC with your right hand, under the tensed AC and make the first loop on the vertcal DHH. Tighten the loop. This will be vertical HH going left to right. Which is also used solo in knotting.
Still holding the AC, make the second loop with the same WC. Tighten the knot, moving loops close together and to the mounting row. This is vertical DHH going left to right.
Take the next AC with your left hand. Again hold it under tension pulling down strictly vertical. Take the same WC with your right hand, under the tensed AC and make the first loop on the vertcal DHH. Tighten the loop. Move it closer both to the mounting row and to the previous vertical DHH.
Still holding the AC, make the second loop with the same WC. Tighten the knot, moving loops closer together, to the mounting row and to the previous vertical DHH.
Using the same WC and changing AC one by one make the row of vertical DHH. Try to tighten your knots evenly.
2. Vertical DHH going right to left.
The next row is knotted from right to left. The WC is the same. ACs are used one after another beginning from the first on the right side.
Take the first from the right AC with your right hand. Hold it under tension pulling down strictly vertical. Take the WC with your left hand under the AC and make a loop.
Tighten the loop. This will be the vertical HH going right to left. Still holding and pulling down the AC make the second loop. Tighten it, moving the loops closer to each other and to the previous row. This will be vertical DHH going right to left. While tightening, please be careful not to leave any loops on the right edge of the work.
Make the vertical DHH on the rest AC using them one by one. Tighten each loop and move it close to each other, the previous row and the previous knot.
General notes to HDHH and Vertical DHH:
The HDHH is wider than vertical DHH that is why it is better to use the wider variety of the LH knot to mount cords for HDHH and simple LH knot for Vertical DHH. This is especially useful for multiple-colores works.
The Vertical DHH is longer than the HDHH.
You can find it helpful to occasionally use HH instead of DHH to make your work more even.
