Common beginner mistakes


Walk into any sewing store, and you'll find hundreds of spools of thread in different colours, materials, weights, and brands. Choosing the right one can feel overwhelming, especially if you're new to sewing.

The good news is that most sewing projects only require a few basic thread types. In this guide, we'll explain the differences and help you choose the right thread for your next project.


What Does Sewing Thread Do?

Sewing thread holds your project together. The right thread creates strong, smooth stitches that last. The wrong thread can lead to:

  • Broken thread
  • Skipped stitches
  • Puckered fabric
  • Weak seams
  • Excess lint in your machine

Matching the thread to your fabric and project helps produce better results and can even improve your sewing machine's performance.


Polyester Thread

Best for:

  • Everyday sewing
  • Clothing
  • Quilting
  • Home décor
  • Crafts

Polyester thread is the most versatile choice for most sewing projects. It's strong, slightly stretchy, colourfast, and works well on both natural and synthetic fabrics.

Our recommendation: A quality all-purpose polyester thread is a great place to start for most sewists.


Cotton Thread

Best for:

  • Quilting
  • Cotton fabrics
  • Traditional piecing

Cotton thread blends beautifully with cotton fabric and is a popular choice among quilters. It has less stretch than polyester and gives quilts a classic finish.


Heavy-Duty Thread

Ideal for:

  • Denim
  • Canvas
  • Bags
  • Outdoor projects
  • Upholstery

This thicker thread provides extra strength for projects that receive a lot of wear.


Embroidery Thread

Embroidery thread is designed for decorative stitching and machine embroidery. It adds shine and colour but isn't intended for everyday construction seams.


Thread Weight Explained

The lower the thread weight number, the thicker the thread.

Some common examples:

Thread WeightCommon Uses
30 wt Decorative quilting, topstitching
40 wt Machine embroidery
50 wt General quilting and sewing
60 wt Fine piecing, delicate fabrics
