How to Create Bobbin Work 7 CREATING BOBBIN WORK (EMBROIDERY) 319 iPress . →The sewing screen is displayed. jPress , and then adjust the tension of the upper thread. For details on adjusting the tension of the upper thread, refer to “Adjusting Thread Tension” on page 233. CAUTION When sewing bobbin work, be sure to select an embroidery pattern for bobbin work. If any other type of pattern is selected, the machine may be damaged. Note Embroidery sewing speed defaults to 350 spm when a bobbin work embroidery pattern is selected. The Settings screen will not allow speed to be adjusted. Memo When an embroidery pattern for bobbin work is selected, the automatic thread cutting function is turned off. Afterward, if a pattern other than one for bobbin work is selected, the automatic thread cutting function is returned to the setting that was selected before the embroidery pattern for bobbin work was chosen. Note Since bobbin work is sewn from the wrong side of the fabric, the pattern shown in the screen appears as a mirror image of the final sewn embroidery. If necessary, flip the image to preview it. In addition, when sewing with the thread colors shown in the sewing screen, select a bobbin thread that matches what is shown in the screen. a Image shown in screen bSewn embroidery (Right side of fabric) Memo With embroidery patterns for bobbin work, the size and thread density cannot be changed. In addition, the automatic thread cutting function cannot be turned on. Memo We recommend a setting between 6 and 8 for the upper thread tension.
CREATING BOBBIN WORK (EMBROIDERY) 320 Start Embroidering aHoop the fabric so the right side of the fabric is facing down with the stabilizer lying on the top. Use an embroidery frame that fits the size of the pattern and then attach the frame to the machine. These patterns are embroidered from the wrong side of the fabric so technically you are working in “reverse” of normal embroidering. aWrong side of fabric bIt is necessary to move to the beginning of stitching so press , and then press . →The embroidery frame moves to the beginning of stitching. cPress . dPress . →The screen changes, and all keys and operation buttons are locked. eUsing the presser foot lever, raise the presser foot. fTo bring the bobbin thread above the fabric, rotate the handwheel counterclockwise while holding the upper thread. gAs shown below, pull the upper thread to pull the bobbin thread up through the fabric. aUpper thread b Bobbin thread CAUTION Always use a stabilizer material for embroidery. Otherwise, the needle may break and cause injuries. Not using a stabilizer material may result in a poor finish to your project. Memo If the bobbin thread cannot be pulled up, use an awl to create small hole to help pull bob- bin thread to surface.
How to Create Bobbin Work 7 CREATING BOBBIN WORK (EMBROIDERY) 321 hPress to unlock all keys and buttons. iLower the presser foot. jWhile holding both the upper thread and the bobbin thread, sew a section of the pattern. kStop the machine, and then tie the upper thread and the bobbin thread together to secure the threads. lStart sewing again to finish the pattern. mRaise the needle and presser foot, remove the embroidery frame, and then cut the upper thread and the bobbin thread. When cutting the threads, be sure to leave an adequate length of thread so they can be properly secured. nUsing a hand sewing needle such as a ribbon embroidering needle, pull the bobbin thread to the top (wrong side) of the fabric, and then tie the upper thread and the bobbin thread together. oRemove the fabric from the embroidery frame, and check the finished embroidery. pIf the desired results could not be achieved, adjust the tension of the bobbin thread and of the upper thread, and then try sewing the pattern again. For more details, refer to “ADJUSTING THE THREAD TENSION” on page 322. Memo If there is a gap between the start point and end point of the pattern, cut the threads, remove the fabric from the machine, and then use a ribbon embroidering needle to hand sew stitches to connect the starting and ending points. a Right side of fabric bWrong side of fabric Memo Check bobbin after each bobbin work embroidery pattern is sewn to make sure there is adequate bobbin thread for the next pattern.
ADJUSTING THE THREAD TENSION 322 ADJUSTING THE THREAD TENSION After sewing trial stitches and checking the sewing results, adjust the thread tensions if necessary. After adjusting the tensions, be sure to sew trial stitches again in order to check the sewing results. ■Adjusting the upper thread tension We recommend a setting between 6 and 8 for the upper thread tension. If utility stitches are being used, refer to “Setting the Thread Tension” on page 79. If embroidery patterns are being used, refer to “Adjusting Thread Tension” on page 233. ■Adjusting the tension of the bobbin thread If the desired stitching cannot be achieved after adjusting the upper thread tension, adjust the tension of the bobbin thread. The tension of the bobbin thread can be adjusted by turning the slotted-head (–) screw on the bobbin case (gray) for bobbin work. a Do not turn the phillips screw (+). b Adjust with a small screwdriver. To increase the tension of the bobbin thread, turn the slotted-head (–) screw 30° to 45° clockwise. To decrease the tension of the bobbin thread, turn the slotted-head (–) screw 30° to 45° counterclockwise. Note Turning the screw on the bobbin case (gray) may push up the spring plate, as shown below. If this occurs, gently press down the spring plate with a screwdriver so it is lower than the top surface of the bobbin case (gray), and then insert the bobbin case into the machine. a Spring plate CAUTION DO NOT adjust the position of the phillips (+) screw on the bobbin case (gray) as this may result in damage to the bobbin case, rendering it useless. If the slotted screw (-) is difficult to turn, do not use force. Turning the screw too much or providing force in either (rotational) direction may cause damage to the bobbin case. Should damage occur, the bobbin case may not maintain proper tension. Note If the bobbin thread tension is tight, the thread cannot be passed through the tension spring when the bobbin is installed in the bobbin case. (Refer to “When tension is not applied to the bobbin thread” on page 312.)
How to Create Bobbin Work 7 TROUBLESHOOTING 323 TROUBLESHOOTING Several solutions for minor problems are described below. If the problem persists, contact your nearest authorized Brother dealer. ■The thread was accidentally cut automatically and the bobbin thread is caught inside the machine aCut the thread near the fabric above the needle plate, and then remove the fabric. a Thread bRemove the bobbin, and then hold it out toward the left side of the machine. cLower the presser foot. dApply slight tension on bobbin thread by holding thread out to the left side of presser foot. Press the “Thread Cutter” button again. ■The pattern is misaligned Refer to “ADJUSTING THE THREAD TENSION” and increase the upper thread tension. If the pattern is still misaligned, reduce the tension of the bobbin thread. Example: Decorative Stitch a Correct tension b The upper thread tension is too loose, or the bobbin thread tension is too tight. ■The bobbin thread catches on the tension spring of the bobbin case Sew with no tension applied to the bobbin thread. (Refer to “When tension is not applied to the bobbin thread” on page 312.) Note If an embroidery pattern was sewn, remove the embroidery frame. CAUTION Do not pull on the thread with excessive force, otherwise the machine may be damaged.

DESIGNING A STITCH 326 DESIGNING A STITCH By using the MY CUSTOM STITCH function, you can register stitches you have created yourself. You can also sew designs combining MY CUSTOM STITCH creations with built-in characters (see page 170). aDraw the stitch design on the grid sheet (part code SA507, GS3:X81277-151). bDecide the spacing of the stitch. * By adjusting the spacing of a stitch, you can create various patterns with one stitch. cPlace points where the pattern intersects with the grid, and connect all the points with a line. dDetermine the x and y coordinates of each of the marked points. Memo Stitches that you create with MY CUSTOM STITCH can be a maximum of 7 mm (approx. 9/32 inch) wide and 37 mm (approx. 1-1/3 inches) long. Stitches can be designed more easily with MY CUSTOM STITCH if you first draw the stitch on the included grid sheet. Memo Simplify the design so that it can be sewn as a continuous line. For a more attractive stitch, close the design by intersecting lines. If the design is to be repeated and linked, the start point and end point of the design should be at the same height. Memo This will determine the stitch design that will be sewn.
