Required Materials
■ Bobbin case and cord guide bobbin cover
a
Bobbin case (gray)
There is a notch at the location indicated by the letter 
“A”.
b
Cord guide bobbin cover (for bobbin work or attaching 
cording using single hole).
There are two small v-shaped tabs on the back of the 
bobbin cover as indicated by the letter “B”.
The tabs help hold the bobbin in place so it does not lift 
up while thick thread is being pulled through.
■ Lower thread
We recommend the following types of threads for 
bobbin work.
* When wide ribbon or heavy weight threads are being used, we
recommend test sewing with and without bobbin case tension 
being applied to see which gives the best stitching results. 
If wide ribbon such as 3.5mm (approx. 1/8 inch) is to be used, 
we recommend that bobbin case tension not be applied. Refer 
to page 11 for more detailed instructions.
■ Upper thread
Upper thread choices can vary depending on the 
finished look you would like to achieve. By using 
sewing machine embroidery thread (polyester), 
multipurpose polyester thread, or monofilament 
(transparent nylon) thread the appearance of a single 
design can be changed many times just by choosing a 
different upper thread weight and/or color.
If you do not wish for the upper thread to be visible, we 
recommend using monofilament thread or polyester 
light weight thread (50wt. or above) that is the same 
color as the lower thread.
■ Needle
Use a needle appropriate for the upper thread and 
fabric being used. Refer to “Fabric/Thread/Needle 
Combinations” (in the chapter “CHANGING THE 
NEEDLE”) in the Instruction and Reference Guide.
■ Presser foot
Utility stitches or decorative stitches: Monogramming 
foot “N”
Free motion sewing: Free motion quilting foot “C”, Free 
motion open toe quilting foot “O” or Free motion echo 
quilting foot “E”
■ Fabric
Be sure to sew trial stitches on a piece of scrap fabric, 
which includes the same threads and fabric as what is 
being used in your project.
No.5 or finer hand embroidery 
thread or decorative thread
Flexible woven ribbon
Fine embroidery ribbon (silk or 
silk-like material) (3.5 mm (approx. 
1/8 inch) or less, recommended)
Note
• Do not use thread heavier than No.5 hand
embroidery thread.
• Some threads may not be appropriate for bobbin
work. Be sure to sew trial stitches before sewing on 
your project.
Note
• The sewing results may be affected by the type of
fabric used. Before sewing your project, be sure to 
sew trial stitches on a piece of scrap fabric that is 
the same as the fabric used in the project.
