Thread Weight and Ply
When it comes to sewing thread, one of the most important aspects to consider is the thread weight. Thread weight refers to how thick or thin the thread is, and it is usually measured in denier or tex. The higher the denier or tex number, the thicker the thread.
Thread weight is an important consideration because it affects how the thread will look and function in your project. For example, if you are sewing a delicate fabric like silk, you will want to use a thinner thread to avoid bulky seams. On the other hand, if you are sewing a heavy fabric like denim, you will want to use a thicker thread to ensure strong seams.
Another important consideration when it comes to sewing thread is ply. Ply refers to the number of strands that are twisted together to make the thread. For example, a 2-ply thread is made up of two strands twisted together, while a 3-ply thread is made up of three strands twisted together.
Ply is important because it affects the strength and thickness of the thread. Generally speaking, a higher ply thread will be stronger and thicker than a lower ply thread. However, a higher ply thread may also be more prone to tangling and breaking, so it’s important to choose the right ply for your project.
When choosing a thread weight and ply, it’s important to consider the type of fabric you will be sewing, as well as the type of stitch you will be using. For example, if you are sewing a stretchy knit fabric, you will want to use a stretchy thread and a zigzag stitch to ensure that the seam stretches with the fabric.
In summary, thread weight and ply are important considerations when choosing a sewing thread. By choosing the right thread weight and ply for your project, you can ensure that your seams are strong, functional, and aesthetically pleasing.
Thread Tension and Stitches
When it comes to sewing, thread tension is crucial for achieving neat and even stitches. The tension is the amount of resistance the thread encounters as it passes through the machine. Too much tension can cause the fabric to pucker, while too little tension can result in loose stitches that easily come undone.
To adjust the thread tension, you can use the tension dial on your sewing machine. The optimal tension setting will depend on the type of fabric and thread you are using. For example, thicker fabrics like denim or leather may require a higher tension setting, while thinner fabrics like silk may require a lower tension setting.
When adjusting the tension, it’s important to test the stitches on a scrap piece of fabric before sewing on your actual project. This will allow you to make any necessary adjustments without ruining your project.
In addition to basic stitches, many sewing machines also offer decorative stitching options. These stitches can add a unique touch to your project, but may require different tension settings than regular stitches. Be sure to consult your sewing machine manual or online resources for the recommended tension settings for specific decorative stitches.
Another important factor to consider is topstitching. Topstitching is a visible stitch that is sewn on the top of the fabric, and is often used for decorative purposes or to reinforce seams. To achieve neat and even topstitching, it’s important to use the appropriate thread and adjust the tension accordingly.
Overall, understanding thread tension and stitches is essential for achieving professional-looking sewing projects. With a little practice and experimentation, you can master the art of thread tension and create beautiful, high-quality garments and accessories.

When it comes to sewing thread, there are several properties that you need to consider before choosing the right thread for your project. In this section, I will discuss some of the most important properties of sewing thread.
Strand
The number of strands in a thread can affect its strength and thickness. A single strand of thread is usually thinner and weaker than a multi-strand thread. The most common types of multi-strand threads are 2-ply, 3-ply, and 4-ply. A 4-ply thread is thicker and stronger than a 2-ply thread.
Diameter
The diameter of a thread is another important property to consider. The thickness of the thread can affect the look and feel of your finished project. Thicker threads are more visible and can add texture to your project. Thinner threads are less visible and can create a more delicate look.
Twist
The twist of a thread refers to the way the strands are twisted together. A high twist thread is stronger and more durable than a low twist thread. However, a high twist thread can also be stiffer and less flexible. A low twist thread is softer and more flexible, but it may not be as strong as a high twist thread.
Elasticity
Elasticity is an important property of sewing thread, especially for stretchy fabrics. A thread with good elasticity can stretch and recover without breaking. Filament threads, which are made of continuous filaments, are generally less elastic than spun threads, which are made of fibers twisted together.
Fibers
Sewing threads can be made of natural fibers, such as cotton and silk, or synthetic fibers, such as polyester and nylon. Natural fibers are usually softer and more breathable than synthetic fibers. However, synthetic fibers are generally stronger and more durable than natural fibers.
Filaments
Filament threads are made of continuous filaments, while spun threads are made of fibers twisted together. Filament threads are generally less elastic than spun threads, but they are stronger and more durable. Spun threads are softer and more flexible, but they may not be as strong as filament threads.
In summary, when choosing a sewing thread, consider its strand, diameter, twist, elasticity, fibers, and filaments. These properties can affect the look, feel, and durability of your finished project.
