To see if the needle is good, 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.

Selecting Thread and Needles
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 TIPPED needle. The blue
tipped needle effectively prevents skipped stitches.
