Hi I bought a Viking 6690 Sewing machine at a garage sale last week end but it doesn't have an instruction manual with it, I'd like to know how to work the machine, but I've never, ever used a sewing machine before. I'm not sure if I even have the thread in the right place. Is there a way I could get an instruction manual? I've looked on the internet, and it directed me to you. I'd really appreciate anything you could help me with. Thank You, Lisa Brown
