How to use

Select a needle of the correct size for the fabric and thread you plan to use. Turn off the sewing machine and raise the needle to its highest position before replacing. Loosen the needle clamp, remove the old needle, and insert the new needle with the flat shank oriented according to your machine manufacturer’s instructions. Tighten the clamp securely, thread the machine following normal procedure, and test-stitch on a scrap of the same fabric to confirm stitch formation and tension.

Recommendations

Use size 12 needles for light- to medium-weight materials and switch to a smaller or larger size if you encounter skipped stitches or fabric damage. Replace needles regularly—after several hours of sewing or when you notice bluntness or bending—to preserve stitch quality and avoid fabric snags.
