Fabric and Needle Chart
• For general sewing, use needle size 11/75 or 14/90.
•
A fine thread and needle should be used for sewing
lightweight fabrics, so the fabric will not be marred.
•
Heavy fabrics require a needle large enough to pierce
the fabric without fraying the needle thread.
• Always test the needle size on a small scrap of the
fabric that will be used for actual sewing.
• In general, use the same thread for the needle and
bobbin.
•
When sewing stretch fabrics, very fine fabrics and
synthetics, use a blue tip needle. The blue tip needle
effectively prevents skipped stitches.
NOTE:
1 x blue tip needles (#11/75), 2 x #11/75 needles and 2
x #14/90 needles are included in the needle case
(Part No. 540401026).

Flat side
To see if the needle is in good condition, place the flat
side of the needle onto something flat (needle plate, glass
etc.). The gap between the needle and the flat surface
should be consistent. Never use a bent or blunt needle.
A damaged needle can cause permanent snags or runs
in knits, fine silks and silk-like fabrics.
