I'm a lefty too. Honestly, the only way to make it easier is to practice, practice, practice. Everything everyone has written is correct. Use a shorter needle, start out with 1 or 2 stitches, and gradually add more. When I was first learning to quilt, I quilted every day, even if only for 15 minutes. The more you do it, the better you get. Remember, you may be left-handed, but you're always in your right mind! :D :mrgreen:
Good luck!
