Taut Line Hitch
if you need a knot that won’t slip under pressure, but can easily move when not under pressure, then the Taut-line hitch is exactly what you need! Scouts may be familiar with using this one to hold up tents. It’s also very helpful when you’re trying to tie something down on a vehicle when you’re moving it.
For this knot, I went with a more basic voronoi, with a little noise, and using displacement in Cycles. I was starting to learn about using different values or saturations in my colors. The image here is another that I relit from the original to give it better contrast and to help see the details more clearly.
