* In general, fine threads and needles are used for sewing fine 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.
