How to Prevent Thread Bunching

If you’re having trouble with your sewing machine creating thread bunches under your fabric, there are a few things you can do to try and prevent it. First, make sure that the needle is inserted correctly and that the machine is properly threaded. If the needle is not inserted correctly, the thread can bunch up as it tries to go through the eye of the needle. Second, check your tension settings.

The tension should be set so that the top thread is slightly tighter than the bottom thread. This will help keep the fabric from bunching up under the needle. Make sure that you are using the correct type of needle for your fabric. A sharp needle will help prevent fabric from bunching up as well.

Troubleshooting Tips for Eliminating Thread Bunching

  1. Check your sewing machine’s tension. If it’s too loose, the top thread will be too loose and the bottom thread will be too tight, causing the fabric to bunch up.
  2. Make sure that your needle is inserted correctly and is the correct size for the type of fabric you’re using.
  3. Be sure to use a new needle when beginning a new project. A dull needle can cause fabric to bunch up.
  4. If you’re using a zigzag stitch, make sure the width is not set too wide, as this can also cause fabric to bunch up.

Other Tips and Advice for Avoiding Thread Bunching

Try a different type or brand of thread. Some threads are more prone to bunching than others.

  • Adjust the tension on your sewing machine. Too much tension can cause thread to bunch up, while too little tension can also lead to problems.
  • Make sure the needle is the correct size and type for the thread you’re using. Using a needle that’s too small can damage the thread and cause it to bunch up.
  • Use a shorter stitch length. This will help prevent the thread from bunching up as it’s being sewn.

Be careful not to sew over any pins or other objects that could damage the thread and cause it to bunch up.


Thread bunching under fabric can definitely be a pesky problem, but with the right troubleshooting tips like using quality thread and needles, adjusting tension levels, and testing your stitch length before starting to sew, it is possible to prevent or even eliminate jbunches. Additionally, if all else fails you can always use one of these simple solutions such as tweezers to untangle any existing messes. Following these steps should ensure that your sewing projects turn out perfectly every time!
