About Bobbin Work

You can create designs, which gives a three-dimensional appearance to the surface of the fabric, by winding the 

bobbin with heavy weight thread or ribbon too thick to be fed through the sewing machine needle and sewing on 

the wrong side of the fabric.

Bobbin work is sewn using the special bobbin case (gray) and bobbin cover with tabs included with this kit.

Required Materials

■

Bobbin Case and Bobbin Cover

a

Bobbin case (gray)

This bobbin case is only for bobbin work. The bobbin 

case will allow you to sew with thick thread or narrow 

ribbon that cannot be inserted through the eye of the 

needle. There is a notch at the location indicated by the 

letter “A”.

b

Bobbin cover

There are ribs “B” on the back of the bobbin cover.

The ribs press down on the bobbin so it is not lifted out 

when thick thread is being fed from it.

■

Lower Thread

We recommend the following types of threads for 

bobbin work.

* If ribbon is to be used, we recommend that tension not be 

applied. Refer to page 6 for more detailed instructions.

■

Upper Thread

Sewing machine embroidery thread (polyester thread) 

or monofilament (transparent nylon) thread.

If you do not wish for the upper thread to be visible, we 

recommend using transparent nylon 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. For details, refer to your machine’s 

Operation Manual.

■

Presser Foot

Utility stitches or decorative stitches: Monogramming 

foot “N”

Free-motion sewing: Use the free-motion quilting foot 

provided with your machine. If you do not have a free-

motion quilting foot, contact your nearest authorized 

dealer to purchase one.

No.5 or finer hand embroidery 

thread or decorative thread

Flexible woven ribbon

(approx. 2mm (approx. 5/64 inch) 

recommended)

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

• If monogramming foot “N” was not provided with 

your machine, use zigzag foot “J”.

• When sewing a pattern described in the machine’s 

Operation Manual and the monogramming foot “N” 

is recommended, be sure to use this foot, otherwise 

the desired results may not be achieved.

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.

Upper Threading

a

Install a needle appropriate for the upper 

thread and fabric to be used.

For details on installing the needle, refer to the 

machine’s Operation Manual.

b

Attach the presser foot.

For the presser foot to be used, refer to see 

“Required Materials” on page 3.

For details on attaching the presser foot, refer to 

the machine’s Operation Manual.

c

Thread the machine with the upper thread.

For details on threading the machine, refer to the 

machine’s Operation Manual.

Preparing the Bobbin Thread

In order to create bobbin work, the bobbin case must 

be replaced with the one for bobbin work.

Before creating bobbin work, clean the bobbin case 

and the race.

a

Raise the needle and presser foot, and then 

turn off the machine.

b

Remove the flat bed attachment.

c

Remove the needle plate cover.

For details on removing the needle plate 

cover, refer to the machine’s Operation 

Manual.

Use the cleaning brush included with the 

machine or a vacuum cleaner to remove any 

lint and dust from the race and its 

surrounding area.

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.

Wind a decorative thread around the bobbin 

by hand. After winding the bobbin so it is 

filled as shown below (about 80%), cut the 

thread.

i

Using scissors carefully trim the thread tail as 

close to the bobbin as possible.

a

Beginning of wound thread

j

Install the bobbin wound with thread.

Whether or not tension should be applied to the 

bobbin thread depends on the type of thread 

being used.

Note

• The bobbin case (gray) cannot be used for sewing in 

any way other than bobbin work. After sewing 

bobbin work, refer back to the steps in “Preparing 

the Bobbin Thread” for removing and cleaning the 

bobbin case (gray), and then reinstall the standard 

bobbin case (black).

 CAUTION

• Be sure to use the bobbin case (gray) when creating 

bobbin work. Using any other bobbin case may 

result in the thread becoming tangled or damage to 

the machine.

• Make sure that the bobbin case is correctly 

installed. If the bobbin case is incorrectly installed, 

the thread may become tangled or the machine may 

be damaged.

 CAUTION

• Be sure to use the machine’s included bobbin or one 

designed specifically for this machine. Using any 

other bobbin may result in damage or injuries.

Note

• Slowly and evenly wind the thread around the 

bobbin.

• For best results, wind the bobbin so the thread is 

snug and not twisted.

 CAUTION

• If thread extends beyond the top of the bobbin too 

much, the thread may become tangled or the 

needle may break.

■

When Tension is Applied to the Bobbin 

Thread

Insert bobbin into bobbin case so the thread unwinds 

from the left side.

Then correctly pass the thread through the tension 

spring as shown below.

a

■

When Tension is Not Applied to the Bobbin 

Thread

If the bobbin thread in the trial stitching is too tight and 

adjusting the bobbin case tension does not help (*As

described in see “Adjusting the Tension of the Bobbin 

Thread” on page 11), do not pass the thread through the 

tension spring.

Hold the bobbin with your left hand so the thread 

unwinds from the right side and hold the end of the 

thread with your right hand.

k

Pull out about 8 cm (approx. 3 inches) of 

bobbin thread.

l

Lightly hold the end of the upper thread while 

turning the handwheel toward you 

(counterclockwise) until the mark on the 

handwheel aligns with the center top of 

machine.

 CAUTION

• When winding the bobbin, make sure the thread is 

not frayed. Sewing with frayed thread may result in 

the thread catching on the tension spring of the 

bobbin case, the thread becoming tangled or 

damage to the machine.

• Do not guide the bobbin thread through the groove 

in the needle plate cover, otherwise the lower 

threading cannot be done correctly.

Insert tweezers through bobbin thread loop 

and pull bobbin thread above the needle 

plate.

o

Align the upper thread and bobbin thread, 

and then pull out about 10 cm (approx. 

4 inches) of the threads and pass them under 

the presser foot toward the rear of the 

machine.

p

Install the needle plate cover and bobbin 

cover.

For details on installing the needle plate cover, 

refer to the machine’s Operation Manual.

q

Install the flat bed attachment.

This completes the upper and lower threading.

 CAUTION

• When creating bobbin work, use the bobbin cover 

with tabs, otherwise the thread may become 

tangled or the needle may break.

Note

• When installing the needle plate cover, do not allow 

it to pinch the thread.

Note

• When installing the flat bed attachment, do not allow 

it to pinch the thread.

• When the bobbin thread is replaced with a new one, 

be sure to repeat the procedure from 

a

 on 

“Preparing the Bobbin Thread”, otherwise the lower 

threading will not be done correctly.
