Frequently Asked Questions
- Why do longarm quilters choose Towa bobbin cases?
- Towa bobbin cases are manufactured to tighter tolerances than standard bobbin cases, providing more consistent and repeatable tension settings. For production studios where consistent stitch quality across many quilts is essential, the precision of a Towa case makes a noticeable difference. They are also exceptionally durable and long-lasting.
- What is the benefit of the Towa tension gauge with this bobbin case?
- The Towa tension gauge (sold separately) allows you to measure the exact tension setting on your Towa bobbin case and record it for future reference. This enables you to return to a specific tension setting precisely when changing thread types, colors, or projects — eliminating trial-and-error re-adjustment.
- What machines use M-style (Class M) bobbins?
- Many longarm machines use M-style bobbins, including APQS machines (Millie, Lenni, Lucey) and others. Check your machine’s manual or manufacturer to confirm bobbin size before ordering.
- How long does a Towa bobbin case typically last?
- With proper care and cleaning, a quality Towa bobbin case can last for years of production use. Regular cleaning of lint from the tension spring and bobbin cavity extends case life significantly.
- Is this bobbin case compatible with pre-wound Magna-Glide bobbins?
- Yes — Towa M-style cases are fully compatible with Magna-Glide Classics and Delights pre-wound M-style bobbins. The precision tension control is particularly valuable when using pre-wound bobbins where consistent tension across the bobbin run is critical.
