Stitch adjustment (thread tension)

Try a few test stitches before you start sewing to check on the condition of the thread. Since thread tension will vary depending on the type of fabric used, do some test sewing when you change fabrics to check on the condition of the thread.

In normal stitches, the upper thread in the bobbin thread will cross in the fabric.

Caution Use either the bobbin that is provided as an accessory or an off-the-shelf metal bobbin. Thread tension cannot be adjusted if you use a plastic bobbin.
