SEWING
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. |
■Upper tension is too loose
Loops appear on the back of the fabric.
Note
●If the upper thread was incorrectly threaded, the upper thread may be too loose. In this case, refer to “Upper threading” on page 17 and rethread the upper thread.
■ Correct tension |
Correct tension is important as too much or too little |
tension will weaken your seams or cause puckers |
on your fabric. |
