There are several different types of polyester sewing thread. These threads vary in appearance and use. All-purpose polyester is the most common. This type is the cheapest, and is suited to general sewing and other purposes. It offers excellent weather resistance and a strong strength-to-size ratio. But there are other types of thread that can be used in particular conditions.
This type of thread is perfect for sewing clothing close to the skin, such as compression gear and intimate apparel. Its construction offers good seam coverage and excellent elasticity. You can find a variety of colors and weights, including those that blend with most fabrics. A specialized thread for specific projects will depend on the type. Ultimately, the right polyester sewing thread will depend on your sewing needs.
The next type of polyester sewing thread is topstitch thread. This thread is usually used for topstitching, but is still functional. You should not put this thread in your bobbin, as it may unwind quickly. Generally, size 90-110 universal needles will work for topstitching. However, there are also topstitching needles that are specifically designed for this type of thread.
While polyester is the most affordable choice, it's not the only type of thread available. For high-end projects, silk thread is also a good choice. This thread is lustrous and takes on a beautiful sheen. Silk thread can be used for both machine sewing and hand sewing. However, it is prone to unraveling if you don't use enough beeswax. You'll be able to see beautiful results with silk thread, and it's also suitable for decorative sewing.
