To check the needle:
Place the flat side of the needle onto something flat
(needle plate, glass etc).
The clearance between the needle and the flat
surface should be consistent.
WARNING:
Never use a bent or blunt needle, which can cause it
to break.

Selecting Thread and Needles
c
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 no be marred.
Heavy fabrics requires a needle large enough to the
fabric without fraying the needle thread.
Always test the needle size on a small pierce of fabric,
which will be used for actual sewing.
In general, use same thread for needle and bobbin.
When sewing stretch, very fine fabrics and synthetics,
use a BLUE TIPPED needle. The blue tipped needle
effectively prevents skipped stitches.
