The thread thickness is usually written as a number followed by a # sign. The thread thickness may also be referred to as the weight and can be written with two numbers and wt. There are many different measurements for thread thickness, but we will stick with the # and weight system here. There is a ratio between thread thickness and weight for quilting and embroidery. When it is smaller, it is thicker, while when it is larger, it is thinner. In comparison to #60/60 wt., #30/30 wt. is much thicker.


A thread’s strength depends on the number of plies it has. Most threads used for quilting, embroidery, and sewing have two or three plies.


In today’s world, nearly all cotton thread is mercerized. A label that says “mercerized cotton” may indicate the label has nothing else to boast about. Since nearly all modern cotton sewing thread is mercerized, we do not print it on our labels. Mercerizing involves treating cotton thread with a solution, causing the fibers to swell, thus allowing dyes to penetrate fibers better and giving them a more attractive appearance.


There are many different types of glazed thread. Glazed threads are coated with wax, starch, resin, or other chemicals. Quite stiffer than unglazed thread, glazed thread has a wire-like look and feel, and is very hard to work with. A glazed cotton thread should only be used for hand quilting.

It is important that you do not let the wax coating of the thread run through your sewing machine’s tension discs. Glazed threads are often not labeled as such. It is possible to determine whether or not a cotton thread is glazed by unwinding a section of two to three feet from the spool and if it twists like a telephone cord, then it is glazed.

Fire Retardant

It’s even used in children’s beds and mattresses due to its ability to withstand extreme heat. The thread is perfect for firefighting gear and race car suits.


Threads with multiple filaments, such as core-spun polyester and smooth multifilament threads, are usually bonded with a special resin to create a tough, but smooth, protective casing.


As part of the process of processing high-quality cotton threads, the thread is passed over a flame at a high speed. Gassed cotton is defined as a thread that burns excess fuzz to produce a high sheen. This is not the case for all threads. If the thread is excessively fuzzy or hairy, it is not gassed. Other terms for gassed cotton include polished cotton and silk finish cotton.

Staple length

In cotton bolls, staple refers to the length of the fiber in a cotton bowl. The longer the staple, the stronger the thread. Unless stated otherwise, assume it is a regular (or short) staple thread. Long staples are better than short/regular staples and extra-long staples are the best. If a cotton thread has an extra-long staple, it will be clearly labeled on its label.
