"What Am I Doing Wrong With Tension?" — A Sewist's Cry for Help

"What Am I Doing Wrong With Tension?" — A Sewist's Cry for Help

A Reddit user recently posted a desperate plea in r/sewhelp that many of us can relate to: "What am I doing wrong with tension? Lately, I can't figure out the right settings for my projects. The pictures show how the bobbin always shows through the front, and there's loose stitches on the back".

They tried every stitch length and tension combination possible, but the closest they could get was keeping tension on one extreme and length on the other—"regardless of the fabric thickness". Worse still, the problem appeared on both of their machines, a Singer Simple and a Singer Heavy Duty.

They had both machines serviced, but "the problem returns almost immediately". After 10 years of sewing experience, they felt like they were "going crazy".

If this sounds familiar, you're not alone. Tension problems are one of the most common—and most frustrating—issues in sewing. Here's what you need to know to fix them, and when it might be time to consider an upgrade.

1. Why Is Tension So Hard to Get Right?

The Reddit user's experience is a classic tension nightmare: bobbin thread showing on top, loose stitches underneath, and no combination of settings seems to work.

The problem often starts with the simplest thing: threading. When the upper thread is not correctly placed in the tension mechanism, the tension dial becomes useless. A single missed guide or a thread that's not fully seated between the tension discs can cause hours of frustration.

What to check first:

• Completely unthread and rethread the machine from scratch

• Ensure the thread is correctly placed in the tension mechanism

• Make sure the presser foot is raised when threading (this opens the tension discs so the thread can seat properly)

• Check that the bobbin is inserted correctly and unwinds in the right direction

The Reddit user's mistake: They tried every combination of settings but may have missed the fundamental step of rethreading correctly. As one guide notes, "unthread and rethread your machine" and "make sure that you follow the correct thread path".

2. Needle and Thread: The Overlooked Culprits

The Reddit user tried adjusting tension and stitch length, but what about their needle and thread?

Needle issues:

• A bent or blunt needle can cause tension problems regardless of your settings

• The wrong needle size for the fabric will create inconsistent stitch formation

• A needle that's not fully inserted or facing the wrong direction affects thread flow

Thread issues:

• Old or low-quality thread can break or stretch unevenly

• Thread that's too thick or too thin for the needle eye creates friction

• Dust and lint between tension discs can cause inconsistent tension

What to check:

• Replace the needle with a fresh one of the correct size for your fabric

• Use good-quality thread appropriate for your machine and fabric

• Clean between the tension discs with a thin piece of card or folded paper

3. The Bobbin: The Hidden Half of the Tension Equation

The Reddit user saw "the bobbin always shows through the front"—a classic sign that bobbin tension is too loose relative to the upper thread.

Bobbin tension problems:

• Bobbin wound unevenly or too full

• Lint or debris in the bobbin case

• Bobbin inserted incorrectly

• Bobbin case tension spring worn or damaged

• A burr on the bobbin case that snags the thread

What to check:

• Remove the bobbin case and clean it thoroughly

• Check that the bobbin unwinds in the correct direction

• Ensure the bobbin is wound evenly and not overfilled

• Test bobbin tension using the "drop test" (the bobbin case should descend about 3-4 inches when held by the thread)

4. Is It the Machine or the Operator?

The Reddit user's machines were serviced, but "the problem returns almost immediately". This suggests one of two things: either the service didn't address the root cause, or there's a fundamental issue with how the machines are being used.

Machine-related issues:

• Timing is off (requires professional adjustment)

• Tension mechanism is worn or damaged

• Hook or bobbin case has burrs that snag thread

Operator-related issues:

• Incorrect threading (the most common cause of tension problems)

• Using the wrong needle or thread for the fabric

• Sewing too fast for the material

• Not cleaning lint regularly

The reality: As one troubleshooting guide notes, "this can happen when the upper thread is not correctly placed in the tension mechanism during the threading process". If you're not threading correctly, no amount of tension adjustment will fix the problem.

5. When Is It Time to Stop Fighting and Upgrade?

The Reddit user has been sewing for 10 years and is using a Singer Simple and a Singer Heavy Duty. These are entry-level and mid-range home machines. While they work for occasional use, they can struggle with consistency—especially as they age.

Signs it's time to upgrade:

• Tension problems persist even after professional servicing

• You're spending more time troubleshooting than sewing

• Your machine can't handle the fabrics you want to use

• You're starting a business or sewing regularly

• You want consistent, professional-quality stitches every time

10. The Bottom Line: Stop Fighting Tension, Start Sewing

The Reddit user's frustration is real and relatable: "I feel like I'm going crazy, am I forgetting something?". After 10 years of sewing, they deserve a machine that works consistently—not one that requires constant adjustment and professional servicing.

Tension problems are almost always fixable. Start with the basics: rethread correctly, replace the needle, clean the bobbin case, and check your thread quality. But if you find yourself constantly fighting your machine—like the Reddit user who had both machines serviced and still had problems—it might be time to consider an upgrade.
