While I've always known a new needle can help, I didn't realize how much until recent years. Most of my sewing was self taught through the years. I have the exact same machine, I keep the ide on for most things. I also grasp the needle and bobbin thread to the back the first few stiches. I don't have the single needle plate, wish I did. I just saw a Martha Pullen show about needles. It was emphasized just how important changing needles often is.
