Sewing projects succeed only if you have the right accessories and materials. This also extends to the sewing thread that holds all the pieces together. Your sewing project typically dictates what kind of thread you should use. All-purpose thread is a safe option in most cases, but you need to consider other types and features as well. Knowing all the differences is an extra step in professionalism that can only help you hone your craft.Type of Sewing
Not all types of sewing are equally easy, many of them requiring different types of thread to succeed. Simple sewing, which includes attaching a piece of fabric to another, is the least demanding, and you can do it with rayon or cotton threads. However, if you need to do some decorating stitches or repair heavy fabrics, you might need other kinds of thread. If the thread remains visible after sewing, as with embroidery, then opt for special embroidery threads, such as sewing silk.Thread Colour
Ideally, the thread colour should match the fabric. One or two shades lighter or darker thread is fine if an exact match is not available. However, if you need to create contrasting stitches, this rule does not apply. Darker shades blend in better, while lighter ones stand out and create contrasting effects.Cotton Thread
Cotton sewing thread is the perfect option for basic sewing, and it comes in several varieties. You can use it when hand sewing or using a sewing machine, but not for sewing knits. Cotton thread is strong with no give and features a silky finish thanks to a special coating. It can break on fluid fabrics but is perfect on delicate fabrics like lingerie materials and sheer fabrics. Medium thickness all-purpose cotton fits most projects, but you might need more specific ones for special tasks like quilting, tatting, and embroidery.Polyester Thread
Polyester sewing threads are strong, but provide a bit of give, being thus suitable for stretchy fabrics, too. A silicone or wax finish allows such threads to slip through the fabric with only a little friction and thus the sewing process is a pleasant one, be it either by hand or on a machine. Some polyester threads are all-purpose threads, which fit most purposes, but are not the best option for embroidery. Invisible thread is also available. Similar to fishing line, it provides strong stitches that remain hidden from the naked eye.
