How To Tell When Your Thread Has Gone Bad

One thing that should be in the mind of every newbie is that the thread is the most important part of sewing. If you don’t have a good quality of thread then, unfortunately, stitches will not be good as well no matter how hard you try. If you are stocking threads and it’s been a long time that you have used most o of them then this is the time to check whether your thread is in a condition to get used or you have to throw it.

A cheap quality thread can affect the performance of the best sewing machine for beginners and it can add up lint as well. It’s important to invest in things which can provide you good outcome instead of getting attracted to the low-quality things. Let’s go through the complete guide and check your thread spool now.


Humidity is the biggest enemy of the thread and if your sewing area is located at the place where you can’t stop humidity then, unfortunately, the thread is not going to last longer. If you are living in a dry climate, then the thread is going to become brittle and this will be a big problem for you to make it soft. If the climate is too soft then your thread will be too sticky and soft.

If you can see any one of the things in your thread it means your thread has gone bad and now you have to use it for the practice purpose. The brittle thread will break again and again while the sticky thread is not going to provide good quality stitches to you. Keep your thread spools in a locker or some cupboard which can keep spools safe from humidity or too much dryness.


Dust is another factor that can destroy your thread and most of the tools you used for the sewing. If you are using a sewing machine and all the tools daily but you don’t clean the place then soon thread is going to be useless.

This thread instead of providing high-quality stitches will start adding lint to your sewing machine and it will affect the performance of the machine. For beginners who just start learning how to sew, it’s advisable to find the best entry level sewing machine to handle your sewing project. Remember to always clean the sewing machine after the work to maintain it.

The biggest disadvantage you can have while using a dusty thread is that all the thread will be in the tension disc and you can see how the machine will start resisting at the time of sewing. You can see how the thread is going to be covered with small grey particles; you can clean it with the help of dry cloth by applying as little pressure as you can. If your thread is in stock for more than 6 months and it’s dusty then it must be too weak to use for the stitching.


One of the things which you should always keep in consideration at the time of setting your sewing area is to keep thread safe from the sunlight. Sunlight has the power to make the color fade no matter if it’s your thread or fabric, if you will expose things for hours in sunlight then you can see the problems later. Store all the fabrics and thread spools into some cupboards.

You don’t have to use lamps near threads that are of high intensity because it can damage the thread and it will be weak. You can use a lamp above your head where the thread is not going to get affected. If you have exposed the thread for too long in the sunlight then you can see how half of the spool will be of another color while the rest of it will be original. The thread will be useless for you and all your money will be wasted invested in it.


You can check the thread with one simple rule and you will be able to get the results whether the thread is able to use or not? If you have an old spool and now you want to use it, check it by releasing a small part from the reel. Now pull it from both ends by wrapping it in your fingers, I prefer to wear gloves or some plastic shopper to save fingers from getting injured.

If the thread is breaking too easily then it means it has become brittle. You can see the small fibers of the thread in the damaged condition as well after breaking the thread. You don’t have to throw the spool but you can use it for practice purposes and for the thread hacks as well. You can use it anywhere in your project but not in professional ones just because of the finishing problem.


Temperature also plays an important role in maintaining sewing products in the room. The first rule is never to leave anything exposed in your sewing room, instead, when you are done with the whole sewing thing, keep everything in the cupboard so no environmental factor can affect things. Too hot temperature can damage and can weaken the thread over time.

The durability of the thread is important and to keep using spools, you need to have an organizer, keep spools in it and close it to save from extreme weather conditions. Another way to keep the thread safe is to neatly wind the thread around the spool in the end and cover it with some plastic bag or sheet. Make sure that you are storing threads at room temperature.


The thread is the delicate part of the stitching and if you are not going to take care of this part then the whole of your project will be too disturbed or weak enough to last for months. Keep an eye on your tools and always make sure that you are storing sewing material into the area where dust and humidity in unreachable.

Never stock thread spools in a big quantity as it is going to waste your money. Just keep extra pairs for emergency purpose and always go for high-quality spools.
