I am just getting back into sewing, [I never did much brfore] but about 10 years ago I got talked into purchasing an $800 Pfaff hobby lock 776 serger and I have used it twice. [That was ten years ago] I now want to try to start learning to sew and cannot find the book….Does anyone know how to thread it? Please tell me you can teach an old dog new tricks. Thanks, Paula
