How Good Sewing Machine Thread Tension Looks Like

When you are sewing, the needle, along with the thread, often interacts with the fabric to create stitches. Basically, when the needle makes its way through the fabric, the top thread and the bobbin thread intertwine to form a stitch. And for the tension to be considered good, your stitch should be uniform and balanced on both sides of the fabric.

Common Sewing Machine Issues

There are several sewing machine issues that can arise while working on your sewing projects. Understanding these problems will help you troubleshoot and address them effectively. Here are some common problems:

Damaged or Wrong Needle

The needle plays a crucial role in the sewing process, and that's why having the right needle matters. Unfortunately, needles often experience wear and tear during use, thus affecting their performance. To keep your stitches looking nice and sharp, it is best if you replace the needle with a new one every 6-8 hours of sewing.

Poor Quality Thread

Purchasing low-quality thread may seem like an affordable option at first, but it can lead to various issues and ultimately cost you more in the long run. Poor-quality threads are more prone to breakage during sewing and can also result in inconsistent tension.

To ensure a more enjoyable sewing experience, always invest in high-quality threads. Look for reputable brands that prioritize using superior materials to create threads that are strong, consistent, and reliable.

Dirty Machine

Over time, dust and lint can accumulate on the inside of your sewing machine, causing various sewing machine issues, including tension problems. If this happens, do not panic. Follow these steps to clean your sewing machine:

Step 1: Turn off your sewing machine.

Step 2: Unplug it from the power source for safety.

Step 3: Refer to your sewing machine's manual to locate the areas that require cleaning and oiling.

Step 4: Use a small brush, such as a lint brush, to gently remove lint and debris from these areas. Be careful not to push the lint further into the machine.

Step 5: Oil the machine according to the manufacturer's instructions.

Step 6: Once you are done cleaning the inside, wipe the exterior of your sewing machine with a clean cloth to remove any dust or lint particles.

Step 7: Plug the machine back in and test it.

What Happens If the Tension Is Loose or Tight?

When the tension on your machine is too loose or too tight, it can cause various issues, including:

How to Fix Sewing Machine Tension Issues?

Achieving proper tension involves finding the right balance between the upper and bobbin thread. Both threads contribute to the final stitch formation, and if one is significantly tighter or looser than the other, it can lead to noticeable tension problems in your stitches.

To fix your sewing machine tension problems, you need to figure out if the issue lies with the top thread or the bobbin thread. Here's how you can do it:

Step 1: Find a plain piece of fabric

Step 2: Choose two contrasting colors of threads

Step 3: Wind the bobbin with one color and the top thread with the other

Step 4: Start sewing on the plain fabric

Step 5: Observe how the two different colors interact and form stitches on the fabric

Adjust Upper Thread Tension

If you see the upper thread on the underside of the fabric, it indicates that the upper tension is too loose and should be adjusted. Start by locating the tension-regulating dial on your sewing machine. In case you are unsure, you can check out the sewing machine's manual for guidance.

Once you've located the dial, turn it slightly clockwise to increase the tension. You can begin with small adjustments and then sew a test fabric sample to observe the stitches. If the upper thread is still loose, continue turning the dial until the stitches appear balanced and the top thread is no longer visible on the bottom.

However, if the top tension is tight, you need to fix it by turning the tension dial counterclockwise in small increments. Continue loosening the tension until the stitches appear even and the bottom thread is no longer visible on the top.

Pro Tip! Ensure to keep a record of any successful tension settings for future reference.

Adjust the Bobbin Tension

Adjusting the bobbin is another crucial step in fixing your sewing machine's tension issues.

If the bobbin tension is too loose or too tight, it can cause imbalanced stitches and thread breakage.

Find the bobbin case on your sewing machine. Pull it out and start turning the screw with a small screwdriver. If you are looking to tighten your bobbin tension, turn the screw slightly right. And if you want to loosen the tension, turn the screw left. After adjusting the bobbin tension, sew a test fabric sample to observe your stitches.

What Is the Right Number for Good Thread Tension?

Determining the right number for good thread tension is not as straightforward as assigning a specific numeric value. The ideal thread tension will vary depending on various factors, including the fabric type and the sewing machine model.

However, it's recommended to start with the default tension setting on your sewing machine and make small adjustments until the desired result is achieved.

Final Thoughts

Proper tension is the backbone of a successful sewing project. It ensures your stitches are even, your thread intertwines flawlessly, and your fabric remains free from distortion. If your machine is experiencing tension problems, follow the steps outlined above to restore the right tension. However, if your sewing machine tension issues don't resolve even after trying everything, it may be time to seek professional help.
