Overview of the machine adjustments
The most appropriate thread tension adjustment for one type of material is not necessarily the ideal adjust- ment for a different material.
The thread tensions required are dictated by the pliability and thickness of the material as well as the type and thickness of the thread.
When necessary, adjust thread tensions as per this table:
| Fabric | Thread | Needles | Stitch length | Thread tension |
