Diagonal Double Half Hitch (left to right): 

1. Using the strand of yarn that is furthest to the left (holding cord), place it diagonally over (from left to right) all other strands (working cords). The placement of your working cord determines the direction and angle of your half hitch knots.  

2. Progressing from left to right, tie a half hitch with cord 2. Pass cord 2 over and then under the holding cord, followed by over itself to form a loop. Pull the knot tightly and push it up to where you want the start to be. 

3. Tie another half hitch knot to make it a double half hitch. 

4. Continue knotting double half hitches with the remaining working cords, ensuring that your holding cord is always positioned diagonally. Each knot will be slightly lower on the holding cord than the previous one. 

5. You will get a row of double half hitches once you have worked your way through all the working cords. 

Diagonal Double Half Hitch (right to left): 

1. Using the strand of yarn that is furthest to the right (holding cord), place it diagonally over (from right to left) all other strands (working cords). 

2. Progressing from right to left, tie a half hitch with cord 7. Pass cord 7 over and then under the holding cord, followed by over itself to form a loop. Tie another half hitch knot to make it a double half hitch. 

3. Continue knotting double half hitches with the remaining working cord to get a row of knots. 

Horizontal Double Half Hitch: 

1. Using the strand of yarn that is furthest to the left (holding cord), place it horizontally over (from left to right) all other strands (working cords). 

2. Progressing from left to right, tie double half hitches with the remaining working cord to get a row of knots.
