I am trying to create the same infinity symbol like in this video.
I know how to use the width tool, but I don't know to create that path that the presenter of that video has already created in that document of Illustrator CS6.
How to create the path for the infinity symbol shown in the video?
EDIT: After following the steps in @Bart Arondson answer, this is my result. By the way, I am using Adobe Caslon Pro font.
