About the Needle
The sewing machine needle is probably the most important part of the sewing machine. Choosing the proper
needle for your sewing project will result in a beautiful finish and fewer problems. Below are some things to keep
in mind about needles.
The smaller the needle number, the finer the needle. As the numbers increase, the needles get thicker.
Use fine needles with lightweight fabrics, and thicker needles with heavyweight fabrics.
To avoid skipped stitches, use ball point needle (golden colored) 90/14 with stretch fabrics.
To avoid skipped stitches, use ball point needle (golden colored) 90/14 when sewing character or decorative
stitches.
Use needle 75/11 for embroidery. Use ball point needle 75/107 for embroidering patterns with short jump
stitches such as alphabet characters when the thread trimming function is turned on. Ball point needles
(golden colored) 90/14 are not recommended for embroidery, as they may bend or break, causing injury.
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.

CAUTION
Be sure to follow the needle, thread, and fabric combinations listed in the table. Using an improper
combination, especially a heavyweight fabric (i.e., denim) with a small needle (i.e., 65/9 - 75/11), may
cause the needle to bend or break, and lead to injury. Also, the seam may be uneven, the fabric may
pucker, or the machine may skip stitches.
