The basic idea of a Voronoi is that you need to find the area that is closest to a given point than any other. Here is my suggested technique:
1. Choose a paper that is fairly transparent to start with. I used standard printer paper and used a light behind it. 2. Choose and mark a set of points that is well distributed. You could probably come up with some sort of mathematical algorithm to choose points for you, but I just dropped a pencil on a piece of paper and then filled in some of the less dense areas. 3. Start folding points on to their nearest 4-6 neighbors, but only crease in between the points. As you get more creases, start extending the creases until they intersect. You will start seeing a pattern of how lines will intersect to create polygonal areas around each point depending on how far each neighbor is. 4. Start folding over creases and treating the intersections in your favorite method. I folded everything over randomly, but you could consider putting proper twists in at the intersections.
