Draw lines toward the edges of the paper from those points.
For each initial line, draw a line which branches off of the initial line which is perpendicular to it, that is going toward another initial line’s start point. End the line when it collides with another line or before then.
Repeat step 3, branching off the lines you draw and the initial lines.
Stop branching in an area when you form a shape with a very small area (e.g., smaller than the tip of a Crayola crayon.)
