Howdy, 
    I had a request to make a custom swing arm bag for a Harley softail.  Now I am no biker and have no idea what a swing arm is!!  That really doesn't matter, though.  What I need to find is a pattern for this type bag.  If I find a pattern, I can make the bag.  Does anyone know where I can find a patters short of tearing up an old one? 
Thanks!
