Note
•
Never use a thread of weight 20 or lower. It may
cause malfunctions.
Memo
•
The lower the thread number, the thicker the
thread; and the higher the needle number, the
thicker the needle.
■
Ball point needle
Use the ball point needle when sewing on stretch
fabrics or fabrics where skipped stitches easily
occur.
Use the ball point needle for best results when
sewing patterns using monogramming foot “N”.
■
Transparent nylon thread
Use a 90/14 to 100/16 needle, regardless of the
fabric or thread.
CAUTION
•
The appropriate fabric, thread and needle
combinations are shown in the table. If the
combination of the fabric, thread and needle
is not correct, particularly when sewing thick
fabrics (such as denim) with thin needles (such
as 65/9 to 75/11), the needle may bend or
break. In addition, the stitching may be uneven
or puckered or there may be skipped stitches.
Checking the needle
Sewing with a bent needle is extremely dangerous
since the needle may break while the machine is
being operated.
Before using the needle, place the flat side of the
needle on a flat surface and check that the distance
between the needle and the flat surface is even.
