What must be done to the needle thread before winding a bobbin?

Winding a bobbin requires the needle thread to be removed completely from the machine. This is essential because the presence of the needle thread can interfere with the bobbin winding process. If the needle thread is left in place, it could create tension issues or cause the machine to jam as the bobbin winds.

When changing thread or preparing a new bobbin, ensuring that the needle thread is out of the way allows for a clean and effective bobbin winding. This practice helps in maintaining optimal functionality of the sewing machine and provides a smooth sewing experience once the bobbin is ready for use.

Taking these steps ensures that the bobbin is filled correctly, without obstruction, which is crucial for consistent stitching quality in any fabric handling or sewing task.
