Sewing thread Brother Alterfil Light Blue 1000 m spool

Brother Alterfil Light Blue 1000 m spool is a polyester sewing thread designed for general sewing and overlocking tasks. The light blue colour and consistent thickness make it suitable for both machine and hand sewing. The 1000 metre length reduces the need for frequent replacement and is intended for garment construction, repairs and decorative stitching where reliable strength and smooth feed are required.

Advantages

The Brother Alterfil polyester thread provides uniform tensile strength and a smooth surface that minimises friction in sewing machines and overlockers. Its consistent diameter supports even stitch formation and reduces breakage during normal garment construction and repair. The 1000 m spool size offers extended use for production runs or larger home projects, while the light blue shade provides good colour matching for a range of fabrics.

How to use

Thread the spool onto your sewing machine or overlocker according to the machine manufacturer's threading path, ensuring correct tension and take-up settings for polyester thread. For hand sewing, cut an appropriate length and tie a small knot at the end or use a needle threader. Test stitch on a fabric scrap to confirm tension, stitch length and colour match before starting the main work. Replace the spool when thread supply runs low to avoid interruptions.

Usage recommendations

Store the spool in a dry, shaded place away from direct sunlight to prevent colour fading and degradation. Use a compatible needle size for polyester thread and check machine tension when changing thread types. For visibly exposed seams, test the light blue shade on a fabric sample to confirm the desired visual effect.
