the Berninas did the best job at finishing the seam straight, without the piece tugging to the side as you ended the seam.
The instructor should have showed you the way to keep the ending straight on any machine if there is a problem of veering. So many teaching have no idea of the basics these days. I was taught this in Home EC class. Keep your left index finger on the left side of the foot toe when coming to the end of a seam. The seam will not veer and stay perfectly straight. Oh how I miss the days of school sewing every school day for an hour. We learned so much.
