	When to Change

If you suspect that a needle is bad, remove it and replace with a new needle. To discard needles safely, place them in an old pill bottle with a child safety

The needle should be changed whenever stitching quality appears to be substandard, if the needle feels rough or if the needle appears to be bent or damaged in any way.

Different types of needles have different expected life-spans. Generally, after several hours of continuous embroidery the needle should be changed. The condition of the needle is particularly important to the quality of stitching in outlines and other detailed or precision areas.

You can check your needles for suitability using these tests. Checking for a bent needle - Remove the needle from the machine and place it on a flat surface with the flat edge of the needle shank down. The needle shaft should be peendicular to the flat surface.

Checking for a burred needle - Needle can develop rough spots called burrs. A burred needle should not be used, as the burr can damage the fabric or embroidery thread. Remove the needle from the machine and glide all sides of the needle point across your fingernail. If the point catches or scratches the surface of your nail, it should be discarded.
