@Randy Burke - THANK YOU! I was going nuts trying to create a new art brush. I was making it vertical (as I had seen in a tutorial) but for some reason EVERY time I set the direction to run parallel to the line I made, Illustrator made it perpendicular. I finally rotated the object I was using as my brush 90 degrees as you mentioned, and it worked! Now the brush follows the direction I specified when setting it up.
