Which Overlocker needle should I use?
Using the correct type, brand and size needle is essential to obtain the perfect stitch.
Needle must be changes periodically and also the right needle should be used for the type of fabric you are sewing.
Your instruction manual will tell you what needle system that you overlocker uses.
Most overlockers use universal needles the same type used in your sewing machine.
Older models may call for industrial needles. The two types of needles are not interchangeable they are different lengths and widths.
Industrial needles have a round shank, house hold needles (universal) have one flat side on the shank when inserting the needle in the machine the flat side of the shank goes to the back.
Also be sure that the needle is “up” as far as it will go.
The right needle is slightly longer that the left one once inserted.
