Questions and answers
Presser foot pressure how do I change
What settings should I use for sewing thru several thicknesses of batting or heavy fabric
Settings for sewing thru thick seams
For sewing through multiple layers of batting or heavy fabric on the Janome 7330 Magnolia, consider the following:
- Use a straight stitch pattern (such as #08, #09, or #10 depending on the need).
- Use the zigzag foot A.
- Set thread tension between 3–7.
- Consider using a machine with a DC motor or a straight stitch machine for more power, as recommended for thick layers.
- Ensure proper presser foot pressure; if adjustable, fine-tune it to prevent fabric bunching.
These settings help manage thick materials and ensure consistent stitching.

I can’t seem to thread the thread(green or blue)
To thread the Janome 7330 Magnolia sewing machine:
1. Raise the presser foot lifter.
2. Turn the power switch on.
3. Hold the needle thread with your finger.
4. Press the Up/Down needle button twice to pick up the bobbin thread.
5. Draw up the needle thread to bring up a loop of the bobbin thread.
6. Pull 10 cm (4") of both threads to the back under the presser foot.
Make sure the needle is properly threaded and the bobbin is correctly inserted and wound. Use thread types and needles compatible with the automatic threader, such as threads #50-90 and needles #11-16.
