The little sweetie has an adorable smile, and I sure wish my first quilt looked half as good as yours! I agree with the advice about youtube for binding tutorials and just about anything else you can name, such as working with the walking foot. If it worked properly for you before and you installed it the same way, probably there's a reason why it's not performing correctly now and you need to find out what that's about rather than risk damaging it or you machine. They're supposed to make life easier, not harder.
