About the threads and the bobbin case when embroidering
Many factors are involved in achieving a beautiful embroidery result. Using the appropriate stabilizer and hooping the fabric in the frame are two important factors mentioned earlier. (Refer to How do I hoop the fabric in the embroidery frame?) Another important point is the appropriateness of the needle and thread being used. See the explanation of threads below. Included with this machine are two bobbin cases. Follow the explanation below.
Thread
Upper thread
Use embroidery thread intended for use with this machine.
Bobbin thread
Use embroidery bobbin thread intended for use with this machine.
If you use threads other than those listed above, the embroidery may not embroider out correctly.
Bobbin case (recommended for sewing and for embroidering with included 60 weight bobbin thread)
Standard bobbin case originally installed in the machine has a green marking on the screw. We recommend using the included embroidery bobbin thread with this bobbin case. Do not adjust the tension screw on this bobbin case with the green marked screw.

Bobbin case (for prewound or other embroidery bobbin threads)
The bobbin case with no color on the screw is set with tighter tension for embroidery with different weights of bobbin threads and a variety of embroidery techniques. This bobbin case is identified with a dark colored mark on the inside of the bobbin cavity. The tension screw on this case can be adjusted if necessary.

When embroidering on large garments (especially jackets or other heavy fabrics), do not let the fabric hang over the table. Otherwise, the embroidery unit cannot move freely and the embroidery frame may strike the needle, causing the needle to bend or break and possibly cause injury. Place the fabric so that it does not hang off the table or hold the fabric to keep it from dragging.
