1. In general, fine threads and needles are used for sewing fine fabrics, thicker threads and
needles are used for sewing heavy fabrics.
2. Always test thread and needle size on a small piece of fabric which will be used for actual
sewing.
3. Use the same thread for needle and bobbin.
4. Use a stabilizer or place a backing for fine or stretchy fabrics, and select the correct
presser foot.
5. It is recommended that a 90/14 needle should be used when embroidering on heavyweight
fabrics or stabilizing products (for example, denim, puffy foam, etc.). A 75/11 needle may
bend or break, which could result in injury.
6. For transparent nylon thread, always use needle 90/14 - 100/16. The same thread is
usually used for the bobbin thread and upper threading.
