How to Fix Common Sewing Machine Problems like Thread Bunching and Skipped Stitches
Sewing is meant to be relaxing and creative — but when your machine starts acting up, it can quickly become frustrating. From thread bunching to skipped stitches, common sewing machine problems can throw off your project. But the good news? Most of these issues are fixable at home with little know-how.
In this blog, we break down sewing machine troubleshooting for beginners and seasoned sewists alike. Whether you’re dealing with sewing machine tension problems, stitches looping underneath, or wondering “Why is my sewing machine skipping stitches?”, we’ve got practical solutions to get you back on track.
Symptoms: Big loops or nests of thread forming under the fabric.
Causes:
Improper threading of the upper thread
Incorrect bobbin insertion
Tension issues
Fixes: Rethread your upper thread completely — don’t just pull and rethread from halfway. Remove and reinsert your bobbin, ensuring it’s threaded correctly in the bobbin case. Check your top tension setting (usually 4 is standard for most fabrics). Clean the bobbin area — lint buildup can also cause looping.
Pro Tip: Always thread your machine with the presser foot up — this ensures the tension discs are open and thread passes through correctly.
2. Problem: Skipped Stitches
(Common search: skipped stitches sewing machine, why is my sewing machine skipping stitches)
Symptoms: Your machine doesn’t form stitches in some places — the thread seems to “jump.”
Causes:
Dull or bent needle
Wrong type of needle for the fabric
Timing issues or uneven feeding
Incorrect threading or tension
Fixes: Change your needle — even a slightly bent or blunt needle can cause skipped stitches. Use the right needle for your fabric (e.g., ballpoint for knits, sharp for woven). Rethread both top thread and bobbin. Adjust thread tension gradually and test on scrap fabric.
3. Problem: Sewing Machine Tension Problems
(Common search: adjusting sewing machine tension)
Symptoms: Stitches are uneven, too loose or too tight. The thread may pull to one side.
Causes:
Tension dial not set properly
Thread not seated correctly in tension discs
Mismatched thread types/top and bottom
Fabric too thick or too thin for settings
Fixes: Start by setting tension to a mid-point (typically 4) and test. Use the same thread type and weight in both the top thread and bobbin. Make small adjustments — tightening or loosening by half a point — and test each time. Don’t forget to match the needle and presser foot to your fabric type.
If you’ve tried all these steps and your machine still misbehaves, it may need servicing. Issues like timing misalignment or motor problems are best left to certified technicians — and at Singer India, we have expert support just a call away.
