* In general, fine threads 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.
