Changing Needles
When sewing stretch, very fine fabrics and synthetics, use a BALL POINT
needle. The blue tipped needle effectively prevents skipped stitches.
When sewing very fine fabrics, sew over a piece of paper to prevent fabric
distorting.
Use the same thread for needle and bobbin.
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.
