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.
