When a string is not a string but a stencil.
I admire Ed Roth and his talents and here is another of his stencils taken from his book Stencils 101.
I am one of those people whose strings seem to come out looking the same every time. I use stencils to remove that responsibility enjoy the creativity of tangling an actual object. This one has been on my mind for a while. The result is not really what I expected and the thought of revisiting this stencil again in the future to see if I get a different result has crossed my mind.
Linda Farmer has included a "string" section to her tangle pattern web site so that you can use a different string then your own or even share yours with others.
