STYLETHREAD -- LET'S TALK SHOP!

I really want to learn this because it would be realy useful for work. I know you can take courses on it, but I'm having such a hard time finding one. The company I work for is going to pay for it, so cost isn't too much of an issue, but I just can't seem to find any schools that offer it. I searced online and I only found online courses, which I don't really want since this is something I feel I would do better with in person. So has any taken a course? Can anyone point me in the right direction?
