Bookbinding threads are one of the required materials for sewing together a journal or book. As this practice has been around for hundreds of years, bookbinding threads used to be made of natural materials like cotton, linen, or even silk. Nowadays, you can also find synthetic bookbinding threads made from nylon or polyester.
What are the best threads for bookbinding? Waxed linen and nylon threads are both strong, easy to use, and quite versatile. In addition, you can choose a three- or four-ply thread with a thickness that suits your bookbinding technique.
In this article, we will discuss various kinds of bookbinding threads available today, what you should know about using each type of thread, and where you can find the best threads for bookbinding.
Bookbinding threads come in a wide range of materials, sizes, and color options, so it can be difficult to know which option is suitable for your bookbinding design and technique. Here’s what you will need to know about the available options.
Bookbinding threads can be made from natural fibers like linen, cotton, and silk and synthetic materials like polyester or nylon. Let’s take a look at each of these materials below.
Linen is a super strong, durable, and long-lasting thread material. As a natural fiber, linen threads have been used for bookbinding since the very beginning of this art.
Nowadays, you can find linen threads in a classic off-white color, as well as bleached and dyed linen threads in a wide range of different color options as well.
Cotton thread is another durable natural thread option. However, cotton thread tends to be thinner and less durable than linen. Mercerized cotton threads are usually much shinier and more durable than traditional cotton threads.
However, since cotton is a natural fiber, it can easily be dyed. That’s why cotton threads are usually available in a wider range of colors compared to linen threads.
Silk threads are also commonly used in rare books. They are super fine threads, yet they are very strong and durable.
However, as a natural material, silk thread is known to be substantially more expensive than linen or cotton threads. That’s why silk threads are only used for high-quality books that can justify this price tag.
Nylon is a newer invention, but it’s a great synthetic thread for bookbinding. Nylon is super durable and very strong, and it’s also more readily available and more affordable than other types of bookbinding threads.
Although nylon is a great synthetic substitute for linen, it doesn’t have the same natural aesthetic as linen threads. For exposed spines, bookbinders still prefer linen threads to nylon threads.
Polyester is another synthetic option, although it is not very popular for bookbinding because the thread is not very strong or durable.
The ply of the thread indicates the number of individual strands of threads that are twisted together to create a single thread. The more plies a thread has, the stronger it is.
However, more plies in a single thread also mean the thread can easily unravel after it’s cut. More plies also tend to bulk up the thread, so we find that three or four plies are enough to add structure to the thread without adding too much thickness.
The thickness of the thread is measured in millimeters. Sometimes, you can see the thickness referred to as ‘gauge’ – the smaller the gauge, the thicker the thread.
Thicker usually means stronger threads, but it may bulk up the spine of the book as well, especially if you are using a minimal bookbinding technique.
Thick threads are also more difficult to sew, and knotting the ends may also cause an eye sore in the book’s spine. Thicker thread options are usually suitable for exposed spine designs.
The ply and thickness of the thread are usually indicated by a gauge/ply number, which would look like 18/3, 12/3, etc.
The first number indicates the thickness of the thread in gauge. The second number indicates the plies in each thread.
For bookbinding, we recommend getting threads that are smaller than 1mm in thickness (a gauge of 12 and up) and 3-ply threads.
Bookbinding threads are usually sold in spools or cards with lengths from 10-280 yards. If you have a favorite thread, then it’s worth it to buy a big spool, as bookbinding threads are usually cheaper when bought in bulk.
However, if you want a lot of color and size options, you can always collect a wide range of sizes, materials, and color options that you can mix and match with different projects.
Natural threads like linen or cotton usually come in a natural color option (off-white). Both natural and synthetic threads are also available in white (bleached threads) as well as different color options (dyed) that will suit a wide range of aesthetics.
Waxed Vs. Unwaxed
Bookbinding threads can also be waxed to prevent the threads from tangling and unraveling when you sew. The beeswax adds a bit of structure to the thread to make it thicker and more durable too. For beginners, we suggest using waxed threads because they are much easier to use.
However, waxed threads tend to be a lot more expensive than unwaxed threads because they require an additional step of processing.
A lot of bookbinders opt to buy unwaxed threads and wax their own threads using beeswax, which is quite easy to do at home. Whether this option is cheaper depends on the type of beeswax that you use to wax your thread.
Spine swell is what you get when the thread that you choose is too thick for your type of binding. The result is a spine that ‘swells’ and bulks up your book rather than adding to the book’s aesthetic.
To prevent spine swell, we suggest choosing the right size thread for your particular bookbinding technique so that the thread doesn’t bulk up the spine.
Closed Vs. Exposed Spine
There are quite a few different bookbinding techniques, and it’s not possible to name them all here, but they can be divided into two different categories: closed spine or exposed spine.
A closed spine is when your stitches are partially or totally hidden in the spine of the book (for example, case binding). An exposed spine is when your stitches are a part of the book’s design, so the threads and your stitches are totally visible (for example, a Coptic binding).
If you want to create a closed spine, it’s best to use a fine thread so that it’s easier to hide the stitches. On the other hand, an exposed spine will require thick and structural threads with nice material because it will add to the final look of your binding.
In addition, the type of paper that you use will need to be taken into account. The thicker the paper, the thicker the thread you will need to use to hold the spine together.

After exploring all the aspects you will need to consider when buying threads for bookbinding, the best options are three- or four-ply linen or nylon/polyester threads that are waxed. In addition, you can customize the thickness and color of the thread to suit your particular project.
