Needs help creating stick figure

Hello, I’m trying to figure how to render a stick figure where the arms, body, and legs are simply lines. All the stick figure tutorials on the Internet seem to be for making solid body stick figures, however I must maintain the style in my comics. Here’s a couple to show the style: http://popstrip.com/sexy-stranger http://popstrip.com/underwater-world As you can see the heads are transparent and the bodies are simply lines. I was able to create a transparent head by adding a transparent material to a sphere, but I’m stuck on getting just lines. Is there any way to get a simple line to render in blender/freestyle? I’ve tried curves, but they have no faces so freestyle doesn’t render them. I’ve tried removing vertices from a cube, but once the faces are gone, nothing renders.

nevermind, i figured it out
