How to Choose the Right Sewing Thread

Choose Polyester Thread for Everyday Sewing

Polyester thread is the most versatile option for modern sewing. It combines strength, flexibility and colourfastness, making it suitable for garments, alterations, home décor projects and general-purpose sewing.

Choose Mercerised Cotton Thread for Quilting & Natural Fabrics

Cotton thread is often preferred for quilting, patchwork and sewing natural fibres such as cotton and linen. Its matte appearance and natural feel make it especially popular among traditional quilters and makers seeking a softer, heritage-inspired finish.

Choose Gutermann Perma Core for Strength & Durability

Gutermann Perma Core combines a polyester filament core with a spun outer layer, creating exceptional strength for workwear, uniforms, bags and garments subject to frequent wear. It is a popular choice among professionals who require reliable seam performance under demanding conditions.

Choose Amann Seracor for Overlock & Serger Machines

Amann Seracor overlock yarns are designed to provide smooth seam finishing, excellent coverage and reliable performance on overlock and serger machines, particularly when working with knitwear, stretch fabrics and garment production.

Professional Thread Selection Rules

Professional makers often follow a few simple guidelines when selecting thread:

• Choose polyester thread for most garment construction, alterations and everyday sewing.

• Choose cotton thread for quilting, patchwork and natural-fibre fabrics.

• Choose Gutermann Perma Core for workwear, uniforms and projects requiring extra seam strength.

• Choose Amann Seracor overlock yarns for seam finishing, knitwear and stretch fabrics.

• Match thread weight to fabric weight whenever possible for stronger, cleaner stitches.

These simple principles help improve stitch quality, reduce thread breakage and achieve more consistent sewing results across a wide variety of sewing applications.

Polyester sewing thread is generally considered the most versatile choice for garments, alterations and home sewing projects because it combines strength, flexibility and durability.

What's the difference between cotton and polyester thread?

Cotton thread offers a natural appearance and is often preferred for quilting and natural-fibre fabrics, while polyester thread provides greater strength, elasticity and resistance to wear.

What thread should I use in an overlock machine?

Overlock machines typically perform best with dedicated overlock yarns such as Amann Seracor, which are designed for smooth seam finishing, excellent coverage and high-speed sewing.

Is Gutermann thread worth it?

Gutermann is widely recognised for its consistent quality, strength and reliability, making it one of the most trusted thread brands among both professionals and hobby sewists worldwide.

What spool size should I choose?

Smaller spools are ideal for occasional sewing and colour-specific projects, while larger cone formats are more economical for workshops, production environments and frequent sewing projects.
