What is thread weight?
Thread weight is a term used to describe the thickness or fineness of a thread. It’s often represented by a number, with lower numbers indicating thicker thread weights and higher numbers indicating finer thread weights. Thread weight is important when choosing a thread for different sewing projects, including embroidery by hand, machine embroidery, quilting, and general sewing.
Embroidery thread comes in various thread weights, including 40 weight, 50 weight, and 60 weight. Cotton thread is often used in embroidery and comes in a range of weights, the most common being 30 weight and 50 weight. Bobbin thread is a lightweight thread used in the bobbin of a sewing machine to create a smooth underside stitch. Polyester thread is another popular thread for machine embroidery and comes in various weights, including 40 weight and 60 weight.
Thicker threads, or heavyweight threads, are often used in machine embroidery to create a bold, textured effect. Machine embroidery thread, made from polyester or rayon, typically comes in 40 or 60 weights. Cotton quilting thread, on the other hand, is usually finer and comes in weights ranging from 50 to 100.
When choosing a thread for a particular project, it’s essential to consider factors like the type of fabric, the needle size and stitch length, and the desired result. The thread spool’s weight can indicate the thread weight number, but it’s important to check the label to be sure. Choosing the right thread weight can help ensure a successful sewing project with a professional finish.
Why is thread weight significant?
Thread weight is a crucial factor when selecting a thread for your sewing project, regardless of whether you’re using a regular sewing machine, serger, or embroidery machine. Most sewing machines are designed to handle different threads, but they work best with the appropriate thread weight.
The weight of a thread refers to the thickness of the thread. Thicker threads have a higher weight, while thinner threads have a lower weight. Choosing the correct thread weight is critical because using the wrong weight can lead to various issues, such as skipping stitches, thread breakage, and tension problems.
For instance, if you use a heavy thread on lightweight fabric, the fabric may pucker and not lay flat. Alternatively, if you use a lightweight thread on thick or heavy fabric, the thread may need to be stronger to hold the fabric together. In either case, the stitching may not be strong enough to withstand normal wear and tear.
Polyester threads are popular for most sewing projects due to their durability and strength. They come in a wide range of weights, from lightweight to heavy, making them suitable for different fabrics and sewing applications. Rayon thread, on the other hand, is known for its smoothness and sheen, making it ideal for embroidery projects.
Serger thread, or overlocking thread, is designed specifically for use with serger machines. It’s typically thinner than regular sewing thread to accommodate the multiple threads used in a serger stitch.
Embroidery threads come in various weights and textures, making them ideal for adding decorative elements to your projects. Machine quilting threads are also available in various weights, allowing you to choose the appropriate thread for your quilting project.
