In general, fine threads and needle are used for
sewing thin fabrics, and thicker threads and
needle are used with heavy fabrics.
Always test threads 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
