How to Fix Skipped Stitches on a Sewing Machine: A Practical Step-by-Step Guide
Few sewing problems are more frustrating than skipped stitches. One moment your machine is sewing perfectly, and the next it’s leaving gaps in the seam, making your work weak and untidy.
The good news is that skipped stitches are usually caused by a few common issues that you can fix yourself in minutes. Before taking your sewing machine to a technician, follow this troubleshooting guide.
What Are Skipped Stitches?
Skipped stitches occur when the sewing machine needle fails to catch the bobbin thread consistently. Instead of producing an even line of stitches, the machine leaves empty spaces between stitches.
Common symptoms include:
- Missing stitches
- Uneven seams
- Loose sections of stitching
- Fabric that easily comes apart
- Irregular stitch patterns
Step 1: Check Your Needle
The needle is the first thing to inspect because it causes most skipped stitch problems.
Possible Problems
- Bent needle
- Blunt needle
- Using wrong needle size
- Using the wrong needle type for the fabric
- Inserting the needle incorrectly
How to Fix It
1. Turn off your sewing machine.
2. Remove the current needle.
3. Roll it on a flat surface. If it moves or shakes unsteadily from side to side, it’s bent.
4. Replace it with a new needle.
5. Ensure the flat side faces the correct direction according to your machine’s manual.
6. Push the needle fully into the holder before tightening the screw.
Match the Needle to the Fabric
| Fabric | Recommended Needle |
|---|---|
| Cotton | Universal 80/12 |
| Denim | Denim 90/14–100/16 |
| Stretch fabrics | Ballpoint or Stretch Needle |
| Silk | Sharp/Microtex Needle |
| Leather | Leather Needle |
Tip: Even if a needle looks fine, replace it after 6–8 hours of sewing or after completing a large project.
Step 2: Rethread the Machine Correctly
Incorrect threading is one of the easiest problems to overlook.
If the upper thread misses a thread guide or isn’t seated properly in the tension discs, skipped stitches can occur.
How to Fix It
1. Raise the presser foot.
2. Remove both the upper thread and the bobbin.
3. Rethread the machine completely.
4. Follow every thread guide.
5. Ensure the thread passes through the take-up lever.
6. Thread the needle from the correct direction.
Always thread the machine with the presser foot raised, allowing the thread to sit correctly between the tension discs.
Step 3: Inspect the Bobbin
A poorly wound or incorrectly inserted bobbin can interrupt stitch formation.
You should Check for:
- Uneven winding
- Damaged bobbin
- Incorrect bobbin type
- Wrong insertion direction
- Lint inside the bobbin case
How to Fix
- Remove the bobbin.
- Clean the bobbin case.
- Rewind the bobbin evenly.
- Insert it exactly as shown in your machine’s manual.
- Replace cracked or damaged bobbins.
Step 4: Clean the Bobbin Area
Lint, broken threads, and dust accumulate around the hook race and feed dogs over time.
This debris prevents the hook from catching the thread consistently.
Steps to Clean
1. Remove the needle plate.
2. Take out the bobbin.
3. Brush away lint.
4. Remove tangled thread.
5. Apply one drop of sewing machine oil if recommended by the manufacturer.
Avoid using compressed air, as it can push lint deeper into the machine.
Step 5: Check Thread Quality
Low-quality or old thread can fray, stretch, or break, causing skipped stitches.
Signs of Poor Thread
- Fuzzy appearance
- Frequent breakage
- Uneven thickness
- Excessive lint
Switch to a high-quality polyester or cotton thread from a trusted brand for smoother, more reliable stitching.
Step 6: Adjust Thread Tension
Incorrect thread tension can prevent proper stitch formation.
If Upper Tension Is Too Tight, it will result in;
- Skipped stitches
- Fabric puckering
- Thread snapping
If Too Loose, it will result in;
- Loops underneath the fabric
- Weak stitches
Start with your machine’s default tension setting and test on a scrap of the same fabric before making small adjustments.
Step 7: Check the Presser Foot
Using the wrong presser foot or failing to lower it properly can affect stitch quality.
Always Make Sure
- The correct foot is installed.
- The foot is securely attached.
- The presser foot is lowered before sewing.
Step 8: Match Needle, Thread, and Fabric
Your sewing machine performs best when these three components work together.
| Fabric | Needle | Thread |
|---|---|---|
| Cotton | Universal 80/12 | Polyester |
| Denim | Denim 100/16 | Heavy-duty polyester |
| Jersey | Ballpoint 75/11 | Polyester |
| Leather | Leather Needle | Heavy-duty polyester |
Using a lightweight needle with thick fabric often results in skipped stitches.
Step 9: Check Machine Timing
If you’ve replaced the needle, rethreaded the machine, cleaned it thoroughly, and the problem persists, the issue may be with the machine’s timing.
The timing determines when the hook catches the loop created by the needle. If the hook arrives too early or too late, stitches will be skipped.
Signs of Timing Problems
- A new needle doesn’t solve the issue.
- The machine skips stitches on every fabric.
The needle occasionally strikes the bobbin case.
- Strange clicking sounds near the hook.
How to Fix
Minor timing adjustments require mechanical precision. Unless you’re experienced with sewing machine repairs, it’s best to have the timing professionally adjusted.
Step 10: Test Before Starting Your Project
Before sewing your actual garment:
- Test on scrap fabric.
- Use the same fabric type.
- Use the same thread.
- Check stitch quality.
- Make any necessary adjustments first.
This simple habit saves time and prevents mistakes on finished projects.
Prevent Skipped Stitches in the Future
Follow these maintenance habits to keep your machine sewing smoothly:
- Replace needles regularly.
- Clean lint after every project.
- Use quality thread.
- Oil your machine when recommended.
- Store your machine in a dust-free environment.
- Use the correct needle for each fabric.
- Change damaged bobbins immediately.
When Should You Visit a Repair Technician?
Consider professional servicing if:
- The machine skips stitches after trying all the steps above.
- The timing is clearly out of alignment.
- The hook assembly is damaged.
- Internal gears are worn.
- The machine makes unusual grinding or knocking noises.
Regular servicing can also prevent small issues from becoming expensive repairs.

Frequently Asked Questions
Why does my sewing machine skip stitches only on stretchy fabric?
Stretch fabrics usually require a ballpoint or stretch needle. A universal needle may miss stitches because it can damage or fail to penetrate knit fibers correctly.
Can a bent needle still sew?
Sometimes, but it often causes skipped stitches, uneven seams, and can even damage the bobbin case. Replace it immediately.
How often should I change my sewing machine needle?
A good rule is every 6–8 hours of sewing or after completing a major project.
Can a cheap thread cause skipped stitches?
Yes. Poor-quality thread may be uneven, produce excess lint, or break easily, all of which can interfere with proper stitch formation.
Should I adjust the timing myself?
Timing adjustments require precision. Unless you have experience repairing sewing machines, it’s usually safer to have a qualified technician handle timing issues.
