SEWING BASICS——————

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.
