For details on starting to sew, refer to “Starting sewing” on page 21.
X Two lines of stitching are sewn parallel to each other.
CAUTION
●When changing the sewing direction, be sure to raise the needle from the fabric, and then raise the presser foot lever and turn the fabric. Otherwise the needle may break or the machine may be damaged.
Thread tension
The tension of the thread will affect the quality of your stitches. You may need to adjust it when you change fabric or thread.
Memo
● We recommend that you do a test sample |
on scrap of a fabric before you start to sew. |
■ Correct tension |
Correct tension is important as too much or too little |
tension will weaken your seams or cause puckers |
—
■Upper tension is too tight
Loops will appear on the surface of the fabric.
Note
●If the bobbin thread was incorrectly threaded, the upper thread may be too tight. In this case, refer to “Lower threading” on page 13 and rethread the bobbin thread.
