PLEASE NOTE:
The needle assortment includes 1 x blue shank
needle (no. 11/75), 2 x no. 11/75 needles and 2 x
no. 14/90 needles.
For optimal sewing results, it is recommend using
Organ needles.
Fabric and Needle Chart
• Use a needle size of 11/75 or 14/90 for general
sewing work.
• A fine thread and a fine needle must be used to
sew lightweight fabric to prevent damage to the
fabric.
• Heavy fabric requires a needle large enough to
pierce the fabric without the needle thread fraying.
• Always test the needle size on a spare section of
the fabric you will be using for sewing.
• In general, use the same thread for the needle
and the bobbin.
PLEASE NOTE:
Use a blue shank needle (available separately)
when sewing flexible fabrics, very fine fabrics and
synthetic fabrics. The blue shank needle effectively prevents skipped stitches.

in order to feed thread to the machine.
To use, pull up the spool pin. Push down for storage.
PLEASE NOTE:
When using thread which has tendency to tangle
around spool pin, thread through the hole of spool
pin as shown. The hole should face the thread
spool.
