Hi,
-The correct answer should be "option B," "Fabric will bunch up under the needle."
The feed dogs are the little teeth-like structures located beneath the needle plate on your sewing machine. They move the fabric forward as you sew, helping to create even stitches. When the feed dogs stop working, the fabric won't be properly guided and can get stuck or bunched up under the needle.
To understand this better, imagine the feed dogs as a conveyor belt that moves the fabric smoothly through the machine. If the conveyor belt suddenly stops, the fabric will pile up and get stuck in one place, causing the machine to sew incorrectly or even get jammed.
In contrast, the other options are not directly related to the feed dogs malfunctioning.
- A. Your needle coming unthreaded is not caused by the feed dogs, but rather by the tension or incorrect threading of the machine.
- C. Not being able to form a lockstitch is related to the machine's bobbin or top thread tension, not the feed dogs.
- D. The thread feed becoming tangled is usually due to issues with the thread tension or the machine's threading, not the feed dogs.
Therefore, the most likely to happen should be "option B," "Fabric will bunch up under the needle."
