Things You'll Need

  • Serger

  • Needles

  • Small screwdriver

A serger can help finish garments and make sure that your garment's edges don't fray after they've been washed and worn a few times. Unfortunately, though, the serger can be a sensitive machine. Because of all the machine's components, there are many things that go wrong. Threads can get knotted together or cut off, and the needles can bend or break altogether. Keeping your serger needles fresh can help minimize the number of things that could go wrong and keep your work running smoothly.


Step 1

Consult your serger's manual for the kind of needles your machine needs.

Step 2

Once you have gotten the needles, look at how your machine holds the needles in place. They are usually held in place with a screw.


Step 3

Unscrew the old needles, and throw them away.

Step 4

When you look at the top of your old needles, you will note a flat edge and a rounded edge. In most sewing machines and sergers, the flat edge will be facing you when it's inserted in the slot.


Step 5

Push the new needle as high as you can into the slot.

Step 6

Take the small screwdriver in your hand and screw the new needle in.

Step 7

Serge a test strip to ensure the new needle is working.


Since you never know when a needle will bend, break or become dull, always keep a set of serger needles handy.
