Sewing is a fun, useful, creative and even relaxing hobby. But there’s nothing fun or relaxing about thread jams. An occasional thread jam is unavoidable. If you are running into frequent thread jams with your sewing machine, however, there are things you can do to help prevent them.

At Fenton Sew and Vac, your local shop for sewing machine repair in St. Louis, MO, we know everything there is to know about thread jams and how to stop them. Here are our top four tips for avoiding thread jams.


Over time lint and dust can accumulate inside your machine. To prevent this, you should clean your machine regularly. However, if you use your machine a lot or, depending on the fabric you use, even regular cleanings may not be able to prevent a clogged machine.

If your machine is clogged, turn off the machine, unthread it, and give it a thorough cleaning. Be sure to give special attention to the bobbin area. You can blow on the inner mechanisms or use a soft brush to remove the dust and lint. You should also make sure that you make oiling your machine a regular part of your maintenance routine.

No Upper Tension

Is your machine jamming up from bunched up thread? This often occurs because the sewing machine doesn’t have enough upper tension to pull the thread up and through the fabric. To fix this problem, simply rethread your machine. Make sure you are rethreading the needle according to your manual.

Bent Needle

It’s easy for a bent or broken needle to go unnoticed. But a bent or damaged needle can wreak havoc with your sewing machine. A bent needle will prevent thread from going through the fabric you are working on, causing your machine to jam.

Remove the needle and check to make sure it’s not bent. If the needle looks fine, but the problem continues, you may have inserted the needle incorrectly or may be using the wrong needle size or type for your project.

Poor Quality Thread

Bargain threads may look attractive in the store, but can end up causing trouble at home. Poor quality threads tend to shred and give off more lint, which can cause tiny knots that will jam up your sewing machine. These types of threads are also more likely to break, which is simply added annoyance.

To prevent these issues, be sure that you are buying quality threads for your machine. Quality thread may cost a little more, but they will save you time and hassle in the long run and even help increase the longevity of your sewing machine.
