A good sewer should know her or his sewing thread. Whether sewing by hand or by machine, this means you should be able to determine the right quality of thread for each of your sewing projects. A good quality sewing thread generally translates to a better sewing experience because it will not break or tangle easily. This is especially true if you sew frequently, and until the wee hours of the morning like I do.
Fortunately, quality thread need not always be the most expensive brand in the market. There are relatively inexpensive threads that are as good as the pricey ones. The trick is to know how to determine thread quality. So here’s how to do it: Inspect a strand of thread by holding it up to a bright light and then inspect how much lint or fray is deviating from it. A high quality thread should only have a few fibers deviating from the main strand and should be tightly bound together. A thread is not like a piece of steel wire, so it will always have some loose fibers but the less there are, usually the higher the quality of your thread.
Sewing threads, as we all know, are made from synthetic or natural fibers, or both, and each has their own useful attributes.
Rayon Sewing Thread – the popular choice, particularly for embroidery
Rayon thread is made from synthetic fibres and is one of the most popular choices among experienced sewers because it is attractive, easily available, and consistent. This type of thread has a good sheen and comes in a big range of colors. However, a disadvantage of rayon is that it is not always colorfast and it can deteriorate over time so requires proper maintenance. The best quality rayon almost always comes from the US or Europe. As strange as it sounds, I’ve read that the best way to store and prolong the life of your rayon thread is to keep it in the freezer! Just be sure to warm it up before you start to sew..
Polyester Sewing Thread – the all-around workhorse
Polyester sewing thread is often the best all-around and all-purpose thread. And for those who want to save money, polyester sewing thread is the popular choice. Because polyester has some give, it will stretch a little making it a good choice for sewing stretchy fabrics like knits. Occasionally manufacturers add some sort of silicone or wax finish to allow the thread to more easily pass through the fabric. Polyester thread is often wrapped in cotton for general purpose use and is also available in a wide array of colors.
Ideal for children’s clothes, polyester does not easily shrink or fade when washed. It has a slightly lesser sheen when compared to rayon thread but the quality is almost the same so that when you use both of them in a single item or design, it will be difficult to see the difference.
Cotton Sewing Thread – beautiful but sometimes not so strong
Often overlooked, cotton thread performs beautifully when used in certain projects. However, because cotton sewing thread has very little stretch or give, it can break more easily than polyester or rayon. It can often be a good choice for sewing lingerie or other delicate fabrics. Sometimes considered as having an heirloom quality to it, this thread provides a soft and lovely sheen to your finished product. Just stay away from finer cotton threads because they tend to be weaker. Best to stick with medium thickness cotton thread and use it on mid-weight cotton, linen or rayon fabric.
Silk Thread – my favorite!
My personal favorite is the silk thread because it absorbs colors brilliantly to give your sewing that rich and brilliant sheen incomparable to other thread types. Strong without being abrasive, it is smooth to use and does not break easily. Silk thread is very fine and flexible. It won’t leave holes in the fabric so it makes a great choice for a basting thread. Since silk thread is expensive, it is often only used for luxurious fabrics and in tailoring. The good news is that silk thread is becoming widely available and it comes in a brilliant range of sizes. This is a thread that is truly fit for royalty!

There are of course many, many other kinds of threads out there including wool, nylon and metallic but we don’t have the space to go into them all here unfortunately. What’s the most exotic kind of thread you’ve ever used? Let us know in the comments below.
Where to Find the Best Thread
