I've been using my sewing machine this weekend, and realised I was using it lefthanded, according to the picture in the instruction book. That shows the right hand nearest the user, feeding the fabric under the foot, while the left hand moves it away behind the needle. I do it the opposite way. But then, I learned on a hand-turned machine, and my right hand was otherwise engaged. You can probably tell people who learned that way from those who learned on electric machines by the way they use their hands.
