I am so right handed. I'm so glad I learned on a hand crank - I didn't realize it but I've always used my left hand to guide fabric and yes I sew straight. I am so right handed. OK It was a habit learned from day one. When I had the hand crank, I ran over a finger and the hand crank got replaced for a FW. I never saw a HC again until a couple years ago. You can bet I put a finger guard on it. I picked up on it right away and amazed myself that I could even flat fell a seam left handed.
