Sewing thread Brother Alterfil 09487 Yellow No.120 1000m

Brother Alterfil 09487 Yellow No.120 1000m is a sewing thread designed for use with home sewing machines and sergers. The No.120 thickness provides a fine to medium filament suitable for a wide range of fabrics, and the 1000 m spool reduces the need for frequent thread changes. This yellow thread is intended for garment construction, hemming, decorative stitching and general repairs where a consistent, smooth thread is required.

Advantages

The Brother Alterfil thread offers uniform thickness and smooth winding on a 1000 m spool, which supports continuous sewing sessions and fewer interruptions. Its No.120 size balances strength and discreteness on fine to medium-weight fabrics, enabling even stitch formation and reduced puckering. The color consistency across the spool helps maintain visual uniformity in seams and decorative work.

Suitable for

• Garment construction and sewing of apparel
• Hemming and seam finishing on lightweight to medium fabrics
• Decorative stitching and topstitching where a fine thread is preferred
• Repairs and alterations on everyday clothing

How to use

Thread the spool into the sewing machine or serger according to the machine manufacturer’s threading path and tension settings. Select an appropriate needle size for No.120 thread and the fabric being sewn — typically a fine universal or microtex needle for lightweight fabrics and a slightly larger needle for medium-weight materials. Adjust stitch length and tension to achieve even stitches without puckering. For decorative work, test stitch settings on a fabric scrap before sewing the final piece.

Usage recommendations

Store the spool in a dry, dust-free place away from direct sunlight to preserve color and thread strength. When changing thread color or after extended storage, run a test seam to confirm tension and color match. For best results on delicate fabrics, use stabilizers or interfacing as needed to prevent distortion.
