## Long description

Brother Alterfil 03947 red 1000 m spool is a general-purpose sewing thread designed for use with home sewing machines and sergers. The continuous 1000-meter length on a single spool provides extended running time for garment construction, repairs and craft projects. The thread's red color (03947) is suitable for visible seams and topstitching as well as matching fabrics where a bright red tone is required.
Advantages
This sewing thread offers a long continuous length that reduces the frequency of spool changes during longer seams and multi-piece projects. It is formulated for consistent feed and even stitch formation in domestic sewing machines and overlockers. The 1000 m spool supports economical use for both occasional repairs and repetitive production tasks at home, and the thread color delivers reliable color matching for red fabrics.
Suitable for
 Home sewing machines for garment construction and alterations
 Overlockers/sergers for seam finishing and edging
 Visible topstitching, decorative seams and craft projects
 Clothing repairs and hemming where a continuous thread length is beneficial
Key specifications
 Color: red (designated 03947)
 Length: 1000 meters per spool
 Intended use: general sewing and machine use, including serging
 Suitable for: domestic sewing machines and overlockers
 Packaging: single large-capacity spool
How to use
Install the spool on the machine's spool pin and thread according to the machine manufacturer's threading path, ensuring proper tension settings for the fabric and stitch type. Use a matching needle type and size for the fabric weight to achieve even stitch formation. For overlockers, thread the machine in the prescribed order and test on a fabric scrap to confirm stitch balance and tension before sewing the main piece.
Usage recommendations
For best results, choose needle size and stitch settings appropriate to the fabric: finer needles and lower tension for lightweight fabrics, larger needles and adjusted tension for heavier materials. Store the spool in a dry, dust-free place to prevent contamination that could affect feeding. When switching colors, remove excess thread tails and trim cleanly to avoid tangles.
