Tie the suspension
Cut two strands of cotton cord about 6 m long, take them double and attach them to the metal ring with the 
lark's head knot. Tie the four strands with the 
spiral knot until the desired length is reached. 
Repeat the process 3 times. 
Finally, take all 4 strands together, pull them through a wooden ring, double them and tie them with the 
winding knot.
Create the lying surface
Attach several 1 m long ribbons to the metal ring with the 
lark's head knot. The more ribbons you take, the tighter the later knotting pattern will be. 
Use the 
staggered square knot to knot all the ribbons all the way round to the middle. 
Bring the ribbons together in the middle and tie them with the 
winding knot.
