Selecting the best sewing machine thread can be difficult for you, especially if you are an experienced sewer or quilter. So, to help you choose the right thread, we will take a look at some of the best sewing machine threads available in the market. Before we touch on this subject, let us point out some essential things you must consider before buying a sewing machine thread.

Things to Consider Before Buying Sewing Machine Thread

Consider these important factors before selecting a sewing thread:

Type of Fabric You Want to Sew

For heavy fabrics, you would need stronger and thicker sewing threads. Examples of strong sewing threads include nylon, polyester, and heavy-duty threads.

The Sewing Machine You’re Using  

If you are using a regular sewing machine, you can sew with thin or thick threads. However, overlock machines and serger machines work best with thin threads.

Type of Stitch You’re Making

Type of stitch you are making is another important consideration. For instance, decorative stitches need smooth threads because these stitches aren’t exposed to tension.

In addition to these things, you must also consider the factors that separate the various types of sewing machine threads to identify the one that’s right for you.

Sewing Machine Thread Differences


Threads are available in a variety of colors. Some threads are single-colored while others are available in a wide array of bobbins or spools. Single-colored threads are suitable for certain stitching projects where you don’t need various color combinations. For instance, if a tailor is stitching curtains for an entire house, they may use a single colored thread to keep things even. On the other hand, multi-colored sewing thread sets are a good option when fabrics of different colors need stitching. For instance, if you are repairing clothes, you would need multi-colored threads.

Tensile Strength

The sheer amount of force a thread is capable of taking before it finally snaps is referred to as tensile strength. It mostly depends on the material of the thread. Generally, the tensile strength of nylon threads is greater than that of polyester threads. Other fabric types, like cotton threads and silk threads, have lower tensile strengths. If you are sewing a light fabric, you can use a thread that has a low tensile strength. On the other hand, if you are sewing heavy materials like leather, then it is best to use a thread with high tensile strength.

Spool Size

It is crucial to determine spool size because it shows how much thread you would need for the project. Determine the spool length that is required for the sewing project before you buy a sewing machine thread to ensure you get the right size.
