- Insert a new needle with the flat side facing the back of the machine, pushing it up as far as it will go.
- Tighten the needle clamp screw securely.
1.4 Bobbin Winding and Insertion
The Janome MyStyle 100 features a top-loading full rotary hook bobbin system for easy access and smooth operation. To wind a bobbin, place an empty bobbin onto the bobbin winder spindle, guide the thread as indicated by the machine's threading path for bobbin winding, and engage the winder. Once full, trim the thread and insert the bobbin into the bobbin case, ensuring the thread feeds correctly through the tension spring.

- Thread the needle from front to back.
- Bring the bobbin thread up through the needle plate opening by turning the handwheel towards you to lower and raise the needle.
2. Operating Your Machine

The Janome MyStyle 100 offers 13 built-in stitches, including a 4-step buttonhole. Use the 'SELECTOR' dial on the front of the machine to choose your desired stitch pattern. Refer to the stitch chart on the machine for visual guidance.
2.2 Stitch Length and Width Adjustment
Adjust stitch length using the 'LENGTH' dial, with a maximum stitch length of 4mm. The maximum stitch width is 5mm, controlled by the machine's internal settings for each stitch pattern. For optimal results, test stitch settings on a scrap piece of your fabric.
