I have a Bernina 820. When you are threading the bobbin look at computer screen. There is a wire that you have to pull the thread through or machine quilting is not going to work right. Tension will be wrong. Takes practice. You should have gotten a small mirror, out underneath the bobbin holkder, you can see the wire. Tricky tho
