The Importance of Good Quality Thread

The needle and thread are the two most important aspects for any sewing machine regardless of the type. Using quality thread will significantly reduce issues with tension, thread breakage and improve stitch quality. 
 
How do I know if I have good quality thread? 
 
1. Test the strength of the thread by breaking a strand with your hand
  • If the thread breaks easily, it is not good quality and will cause numerous issues while sewing such as frequent thread breaks 
  • If the thread does not break easily and requires a good amount of force to break, it is more than likely quality thread. 
  • While this test will help determine thread quality, it is not the only factor and should be used in conjunction with other testing methods.

2. Hold a strand of thread up to a light and see how many fibers fan out from the strand

  • If a lot of fibers are sticking out from the strand, it is not good quality and will cause tension issues while also causing excessive lint to be produced which can cause issues with your machine.
  • If little to no fibers stick out from the strand, it is likely quality thread.
  • Some fibers will naturally be more "fuzzy" or fan out than other fibers. The fiber content of your thread needs to be considered when determining thread quality.

3. Hold out a strand of thread and check for a consistent width 

  • If the thread has an inconsistent width, it is low quality and will cause issues. The tension unit will not be able to properly apply tension and it will create poor quality and inconsistent stitches.
  • If the thread is a consistent width, the thread is more than likely quality. The consistent thread width will allow the tension unit to properly apply tension at all times which will create good quality and consistent stitching. 
 

This example shows a good

quality thread because it has

little to no fuzz fanning out

and it has a consistent 

width. 

 

This example shows poor 

quality thread because it

has a lot of fuzz fanning out

all directions and an

inconsistent width. 

Notes to Consider 

Thread Breakage:
Some thread will naturally break more easily than others because of the type of fiber that is used. For example, cotton thread will be easier to break than polyester thread because of the type and length of the fiber. Cotton is a natural fiber short in length which makes the fiber naturally weaker than long synthetic fibers such as polyester. We will go into more detail about the difference and types of fibers at a later date.
 
What can I use poor quality thread for?
If you have a lot of thread that does not work well in your machine because of inconsistency in the thread width or it breaks too easily, try using your poor quality thread for hand sewing or temporary stitching such as basting.
