This is the tutorial I put together for the Six Intersecting Stars (also known as Modular 20 in my gallery). I apologize if any of the steps are a bit confusing, but I don't really knwo how to explain this very well. a lot of trial and error on your part will be required. A LOT! On the other hand, at least you have refferance pictures. I didn't. anyhow, hav fun with it!
(Also, I really don't care about typoes. Let it go. If you are goign to critique it, then go ahead and mention them.)

(I didn't invent it. I'm only explaining how to do it!)
