Continuous Random Line

I have been working these days on this and defintely the drawing that I am looking for needs lines, with Vertexes is not possible to get the complexity of the forms that I get using lines . If I can not colour that spaces between lines, can I know somehow where are the points of the random lines to replicate designs later with vertexes?

void setup() {
  size(600, 600);
  background(255,255,255);
  
  float x1 = random(0, 600);
  float y1 = random(0, 600);
  float x2 = random(0, 600);
  float y2 = random(0, 600); 
  float x3 = random(0, 600);
  float y3 = random(0, 600);
  float x4 = random(0, 600);
  float y4 = random(0, 600);
  float x5 = random(0, 600);
  float y5 = random(0, 600);
  float x6 = random(0, 600);
  float y6 = random(0, 600);  
  float x7 = random(0, 600);
  float y7 = random(0, 600);
  float x8 = random(0, 600);
  float y8 = random(0, 600);
  float x9 = random(0, 600);
  float y9 = random(0, 600); 
  float x10 = random(0, 600);
  float y10 = random(0, 600);
  float x11 = random(0, 600);
  float y11 = random(0, 600);
  float x12 = random(0, 600);
  float y12 = random(0, 600);
 
  
  stroke(0, 0, 0);
  strokeWeight(3);
  line(x1, y1, x2, y2);
  line(x2, y2, x3, y3);
  line(x3, y3, x4, y4);
  line(x4, y4, x5, y5);
  line(x5, y5, x6, y6);
  line(x6, y6, x7, y7);

  line(x8, y8, x9, y9);

  line(x10, y10, x11, y11);
  line(x11, y11, x12, y12);
  line(x12, y12, x1,y1);
