NEEDLE, THREAD AND FABRIC CHART
Your fabric will determine the choice of a needle and thread.
The following table is a practical guide to needle and thread
selection. Always refer to it before a new sewing project. And
be sure to use the same size and type of thread in the bobbin
as in the top thread supply.
* Do not use on stretch fabrics.
* For best sewing results, always use a Singer Branded Needle.

Helpful Hint: Placing a scrap of fabric under the
presser foot and lowering the presser foot makes
it easier to change the needle and will preclude
dropping the needle into the needle plate slot.
NOTE: Tighten snugly, but do not over tighten.
