Along with thread, needles are very important to stitch formation. Many "mechanical" problems and damage
to fabrics can be traced to a bent, damages, or incorrect size or type needle. Approximately 60% of all
needles made are discarded at some stage of production. When selecting the correct needle for any sewing
project, three things must be considered:
Needle system – 130/705H
Needle point – to assure stitch formation and avoid fabric damage
Needle size – small size for lightweight fabrics; larger needle for heavier fabrics
If the needle is:
Too small – the thread can't stay in the groove to form a loop to be picked up by the hook point
Bent – thread loop forms too far away from hook point; hook can't enter loop to form stitch
Blunt – needle won't pierce fabric so no thread loop forms to make a stitch

Need To Know
• Needle should be changed every 4-6
hours of sewing. The needle is the most
inexpensive part in your sewing machine
but is one of the most crucial for getting
good results and keeping your machine
running well. Don't let false economy
keep you from doing what is best for
your sewing projects and your machine.
• European needles are chrome-plated
to glide in and out of fabric easily.
• The selected thread should fit in the
groove on the front of the needle. If it
isn't protected by the groove, a needle
with a larger groove should be used.
• Always make sure the needle is fully
inserted as high as possible when
installing a new one.
