* In general, fine thread and needles are used for
sewing thin fabrics, and thicker threads and needles
are used for sewing heavy fabrics. Always test
thread and needle size on a small piece of fabric
which will be used for actual sewing.
* Use the 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.
* When sewing very fine fabrics, sew over a piece of
paper to prevent yarn distortion.
