Contour to line node. Some questions

Hi. I have little problems with my tracking patch. I need to texturise contour of object by lines, but when i use line node i just get simple object contour. I understand, thats i need remake spread, thats come out from contour freeframe, but cant understand how. I attached image to describe problem.

Perhaps a dirty way would be, mix up that contour spread at random (read here), and when you connect the lines you could end up with something link your drawing.
