That is a great solution. I find that more than the drawing, the difficulty is the "visualization" of the path. Without the visualization, it is even harder to draw it. I had the same problem. I had to do it and redo it several times, so don't despair!
Once you have a path, you have to adjust it to the thickness of the rope itself, but you can always keep that path. In fact, maybe even save it as a preset shape! So you won't have to redo anything from scratch!
