Hi, I'm new to this board and wanted to say hello and ask a question. I don't know if it's me or my machine, but when I try to sew a straight line, it goes fine for a few inches, and then seems to shift sideways, and then go straight again. Has anyone else had this happen, or is it just me being unsteady. I took the machine apart and oiled all the places, well except for the one to the far right, by the wheel. I think the tensions are fine, as the stitch itself looks OK. I'm stumped. Can anyone help me? Thanks, Bebes
