Use the supplied plastic X52800-120 bobbin or the same type: 11.5 mm (about 7/16 inch) high, Class 15 type. Insert it beneath the top bobbin cover so the thread unwinds left. For utility sewing, use thread appropriate for the fabric, normally the same as the upper thread. The removable standard case is green-marked XG2058-001 and is recommended with the included or recommended 60-weight embroidery bobbin thread; do not adjust its tension screw.
