Product Information
Full details
The Janome Low Tension Bobbin Case is an essential accessory for intermediate and advanced quilters looking to achieve professional-grade stitch quality during free-motion quilting. By providing lower, more consistent thread tension, this specialized bobbin case prevents common puckering and nesting issues when using a convertible free-motion quilting foot. While it is highly effective for specific quilting techniques, it is not intended for standard daily sewing and must be swapped out when switching back to regular projects.

FAQs
Can I use this for normal sewing?
No, it is specifically designed for free-motion quilting and will cause uneven stitching on standard sewing projects.
Does this replace my standard bobbin case?
It serves as an alternative for specific tasks. You should keep your original case for general sewing and swap them as needed.
Do I need to adjust my top tension when using this?
Yes, you will typically need to lower your top tension to achieve a balanced stitch with this bobbin case.
How do I know if my machine is compatible?
Check your manual for compatibility with Janome low-tension bobbin accessories, or look for the top-loading drop-in bobbin system common in Janome quilting machines.
What is the blue arrow for?
The blue arrow serves as a quick visual identifier so you can easily distinguish the low-tension case from your regular bobbin case.
Troubleshooting
Stitches are still pulling to the top of the fabric.
Lower your machine's top tension setting further. Ensure the thread is correctly seated in the bobbin case tension spring.
Bobbin thread is bunching up underneath.
This indicates the tension is too loose; check that the bobbin is wound evenly and increase your top tension slightly.
The bobbin case won't click into the machine.
Check the bobbin area for lint buildup and ensure the bobbin is fully inserted into the case.

Compatibility
The MC11000 Low Tension Bobbin Case is compatible with most Janome machines that utilize a top-loading bobbin system, including models in the Horizon Memory Craft series and various QDC (Quilt Decor Craft) machines. Consult your machine's manual to ensure it supports low-tension bobbin accessories.
Care
Keep the bobbin area free of lint. Dust buildup can interfere with the precision tension spring inside the case. If the case becomes dirty, use a soft, dry brush to gently clean the interior area. Never submerge the bobbin case in water or use solvents.
