I'm sewing on a Brother HC1850. I was using a Singer 7463 and had the same problem using that one too. I gave myself a larger seam allowance, half inch, and have the needle as far right as it will go because it would drift so far that it would eventually uncover the right side of the feed dog.
I know both these machines are capable of wide stitches. Is there something I can do to prevent this? Would a walking foot aid in this situation?
