I just attended the Houston International Quilt Festival and decided to purchase some M pre-wound quilt bobbins for myHQ16.
The man said to make sure I remove the anti-backlash spring on the bobbin casing before inserting the rewound bobbin.
I am not sure if my bobbin case has this type spring. I only see something C-shaped on the inside of my bobbin case.
I do not want to mess up my machine.
Can someone help me with this?
