Troubleshooting Tension Problems for Machine Quilting and Free Motion Quilting
1. Thread Bunching Under Fabric
Thread bunching creates those annoying clusters of tangled thread underneath your fabric. While the top stitching might look perfectly fine, the underside tells a different story - messy loops or knots. If you’re dealing with this, here’s how to fix it.
Start by checking the upper threading. This is often the main reason for thread bunching. If the thread isn’t properly guided through all the tension discs and guides, it throws off the balance between the upper and bobbin threads. To fix this, remove the upper thread completely and re-thread it carefully, following the steps outlined in your machine’s manual.
Next, take a look at the bobbin installation. An unevenly wound bobbin or one inserted incorrectly can also cause trouble. Make sure the bobbin is wound smoothly, without any loose or overly tight spots. Then, ensure it’s placed in the bobbin case correctly. Most machines require the thread to unwind counterclockwise, but double-check your machine’s specific instructions.
If re-threading doesn’t solve the issue, the problem might be tension imbalances. Uneven tension between the upper thread and the bobbin thread can result in bunching. Adjust the upper tension dial slightly - make small changes and test on scrap fabric until the stitching looks even.
Lastly, don’t overlook needle problems. A dull, bent, or incorrect needle for your fabric can cause snags and tangles. Replace the needle with a new one that matches your fabric type and weight. Also, make sure it’s inserted all the way and oriented correctly.
2. Skipped Stitches
Skipped stitches can leave noticeable gaps in your seams, making them weaker and less durable. These issues often arise from needle problems or incorrect machine settings.
Start by inspecting your needle. A dull or damaged needle is the most common culprit. Even if it looks fine, the needle might have a burr or a bent tip that prevents it from piercing the fabric properly. To avoid this, replace your needle after about 8-10 hours of quilting or as soon as you notice skipped stitches.
Using the wrong needle size can also lead to skipping. For heavier fabrics, choose a size 90/14 or 100/16 needle, while lighter fabrics work best with a 70/10 or 80/12 needle. A needle that's too small can strain the machine, causing it to flex and miss the bobbin thread.
Next, double-check your needle insertion. Make sure the needle is fully inserted and tightened, with the flat side facing the back of the machine. Proper alignment is key for maintaining correct timing.
Tension issues between the upper thread and bobbin thread are another common cause. If the upper thread tension is too tight, it can disrupt the loop formation. Try lowering the upper tension setting slightly and test on a scrap piece of fabric to find the right balance.
Lastly, evaluate your thread quality and type. Inferior or old thread can cause jamming or tension inconsistencies. Opt for high-quality cotton or polyester thread specifically designed for machine quilting to ensure smooth stitching.
3. Fabric Shifting or Misalignment
Fabric shifting can throw off your quilt design and cause seams to misalign. When fabric moves during quilting, it often leads to uneven seams, puckering, or blocks that don’t line up - undoing hours of careful work.
One of the main culprits is not enough basting or pinning. To keep everything in place, secure your quilt sandwich with safety pins or quilting clips every 3–4 inches, starting from the center and working outward. Pay extra attention to the edges and corners since fabric tends to shift more in these areas. Along with basting, your machine settings play a big role in keeping fabric aligned.
For instance, feed dog settings are key to fabric control. If the feed dogs are set too low, they won’t grip the fabric properly, allowing the layers to slide against each other. Make sure your feed dogs are raised and clean - use a small quilting brush to remove any lint that might affect their performance.
You should also adjust the quilting foot pressure to manage fabric movement. Too much pressure can stretch the fabric, while too little lets it slip. Most sewing machines have a pressure adjustment dial; if you notice the top layer bunching or stretching ahead of the bottom, try reducing the pressure slightly.
Match your basting and machine settings to the fabric type and weight. Lightweight or slippery fabrics, like satin or fine cotton, are more likely to shift than sturdy quilting cottons. For these trickier materials, add spray basting to your safety pins and switch to a walking foot. A walking foot helps feed all layers evenly through the machine, which is especially useful for fabrics prone to slipping. Proper basting combined with tailored machine settings ensures smooth fabric feeding.
If you’re doing free-motion quilting, don’t overlook hoop tension. The hoop should hold the fabric firmly enough to prevent distortion but not so tight that it causes pulling. A well-tensioned hoop allows the needle to move cleanly through the fabric without tugging it in different directions.
4. Thread Breaking
Nothing halts your quilting flow quite like a thread that keeps snapping. This frustrating issue typically boils down to three main culprits: incorrect threading, tension problems, or low-quality thread. Identifying the root cause can save you time and frustration, so you can get back to stitching.
Start by re-threading your machine completely, from the spool all the way to the needle. Even seasoned quilters can occasionally miss a thread guide or tension disc, which can create weak spots where the thread is more likely to snap. Use your machine’s threading diagram as a guide, ensuring the thread passes through every guide, disc, and take-up lever. Pay close attention to the tension discs - the thread should sit securely between them, not hover loosely on top. If this step doesn’t fix the problem, it’s time to look at your tension settings.
Adjust your upper thread tension if re-threading doesn’t do the trick. Tension that’s too tight puts unnecessary strain on the thread, leading to frequent breaks. Most machines have a tension dial numbered 1 through 9, with 4 or 5 being ideal for quilting cotton. If your thread keeps snapping, try lowering the tension one step at a time until the issue resolves.
The quality of your thread matters more than you might think. Bargain or old thread often becomes brittle, snapping under the stress of quilting. Exposure to sunlight and humidity can also weaken thread over time. Invest in high-quality quilting thread designed specifically for machine piecing and quilting - it holds up far better under repeated needle punctures.
Finally, don’t overlook your needle. A dull or damaged needle can fray the thread, creating weak spots that lead to breaks. Replace your needle every 8–10 hours of quilting or sooner if you notice burrs or a bent tip. Also, make sure your needle size matches your thread weight - a needle that’s too small forces the thread through an eye that’s too tight, causing friction and, ultimately, breakage.
5. Uneven or Loose Stitches
Uneven stitches can disrupt the beauty of your quilt, but the good news is that they’re often easy to fix with some careful adjustments. When stitches vary in size or appear loose and loopy, the usual culprits are tension issues, threading mistakes, or mismatched needles and thread.
Start by checking your bobbin tension, as this is a common cause of uneven stitches. To test it, hold the bobbin case by the thread and give it a gentle tap. The case should drop slowly and evenly. If it falls too quickly, the tension is too loose. If it doesn’t move at all, the tension is too tight. Most bobbin cases have a small screw for adjustments - turn it just a quarter-turn at a time to avoid overcorrecting.
If the bobbin tension seems fine, re-thread your machine carefully. Make sure the thread is properly seated in all guides and tension discs. If the thread sits on top of the tension discs instead of between them, your stitches may end up loose and inconsistent.
Choose the right needle for your thread. For standard cotton quilting thread, a 90/14 universal needle works well. If you’re using a heavier thread, opt for a larger needle, like a 100/16. A needle that’s too small can create friction as the thread struggles through the eye, leading to uneven tension. On the flip side, an oversized needle can leave holes too big to hold the thread securely, resulting in loose stitches.
Finally, test your tension settings on a scrap piece of fabric before diving into your quilt. Start with your machine’s default tension (usually around 4 or 5) and make small adjustments until the upper and bobbin threads lock evenly in the middle of the fabric layers. The goal is for the stitches to look identical on both the top and bottom of your quilt sandwich.
6. Needle Breaking
Nothing disrupts quilting like a broken needle. This common issue often happens when pins are struck, the wrong needle is used, or thick layers are handled too quickly. Thankfully, a few simple adjustments can help you avoid most needle breaks.
First, always remove pins before they reach the needle. Even if it seems safe to sew over them, it’s not worth the risk. A pin strike can instantly snap your needle, and the broken pieces might damage your machine’s timing or scratch the bobbin case.
Next, make sure you’re using the right needle for the job. When working with thick layers, opt for a quilting needle specifically designed to handle multiple fabrics. Using a needle that's too small can increase stress and lead to breakage. For lightweight cotton fabrics, a standard 80/12 universal needle works well. But when sewing through several layers of batting and backing, switch to a sturdier 90/14 or 100/16 needle.
Also, slow down when tackling bulky sections. Areas where seams intersect can create thick spots with multiple layers of fabric and batting. If your machine’s motor strains or the needle starts to bend, reduce your speed. Let the machine handle these tough spots at its own pace instead of forcing it through.
Finally, ensure your needle is properly secured and aligned before you start sewing. Insert it with the flat side facing the back, push it all the way up, and tighten the screw firmly. A loose needle can wobble as it moves, creating extra stress that may cause it to snap.
7. Machine Not Feeding Fabric Properly
When your quilting machine struggles to feed fabric smoothly, it can throw off your entire project. This issue often comes down to three main culprits: lowered feed dogs, incorrect presser foot pressure, or fabric that's too thick for the current settings.
First, check the feed dogs - those small metal teeth beneath the needle that guide the fabric. Quilters often lower the feed dogs for free-motion quilting but forget to raise them back up for regular sewing. Look for the lever or dial near the needle, usually marked with up/down arrows, and ensure the feed dogs are raised. Also, inspect them for lint or thread buildup, as debris can interfere with their function.
Next, consider the presser foot pressure. Too much pressure can make it hard to move thick fabrics, while too little pressure won't grip lightweight fabrics properly. Use the machine’s pressure dial to adjust accordingly. For standard quilting cotton, medium pressure usually works best. If you're working with layers or batting, reduce the pressure slightly to allow smoother movement.
For thick seams or bulky layers, a walking foot can be a game-changer. It helps feed multiple layers evenly and prevents drag. If you're using a quarter-inch foot, double-check that it isn't causing resistance.
If the problem persists, take a moment to clean around the feed dogs. Lint and thread fragments can accumulate and disrupt fabric movement. These simple adjustments can help keep your fabric flowing smoothly and ensure your machine operates reliably throughout your quilting projects.

8. Bobbin Jamming or Not Spinning
When your bobbin jams or refuses to spin, it can bring your quilting to a sudden halt. This common issue often arises from improper bobbin winding, incorrect placement in the bobbin case, or an accumulation of lint and debris in the bobbin area.
Start by inspecting the bobbin winding. The thread should be wrapped evenly, without any overlaps or loose sections. If you notice the thread bunching up on one side or wound too loosely, remove it completely and rewind the bobbin. Go at a slower and steady pace to ensure the thread feeds evenly.
Next, check the bobbin placement in its case. For most machines, the thread should pull off in a counterclockwise direction, but always refer to your machine's manual for the correct orientation. If the bobbin feels crooked or doesn’t settle into place easily, remove it and reposition it. A properly seated bobbin should lie flat and spin freely without resistance.
Another frequent cause is lint buildup around the bobbin case. Over time, cotton fabrics can shed tiny fibers that accumulate and create friction, disrupting smooth bobbin movement. Remove the bobbin and its case, then clean the area thoroughly using a small brush or compressed air. Pay close attention to the tension spring and the small hook that catches the upper thread, as these areas are prone to collecting debris.
If none of these steps resolve the issue, and your bobbin case has an adjustable tension screw, avoid making adjustments unless you have experience with tension settings. Misadjusting this screw can lead to further complications.
9. Stitches Forming at Odd Angles
When stitches start forming at unusual angles, it’s often a sign of tension issues. A quick fix to try is adjusting the bobbin tension. As one quilter shared:
"Try tightening the tension on your bobbin. That is what my dealer advised when my Bernina started to have the bobbin thread not quite straight. It worked."
- Tartan, Power Poster, Quiltingboard Forums
After addressing the bobbin tension, turn your attention to the top thread tension. If the bobbin thread shows up on the top of your fabric and causes puckering, lower the top tension. On the other hand, if the bobbin thread loops underneath, increase the top tension. Use scrap fabric to test small, gradual adjustments until the stitches straighten out.
Lastly, make sure your needle matches your thread weight. Using the wrong needle size can create unnecessary friction, which disrupts tension and leads to uneven stitches.
10. Machine Making Unusual Noises
Strange noises coming from your sewing machine often point to loose parts, poor lubrication, or lint buildup. The good news? These problems are usually easy to fix. Here’s what you can do before diving into your machine manual for further help.
Start by inspecting and tightening key parts, such as the needle plate, foot holder, and side casing, using a screwdriver. Even slightly loose components can cause rattling or clicking sounds that might seem alarming but are often minor issues.
Next, tackle lint buildup. Keeping your machine free of lint is essential for smooth operation and can also prevent more serious problems. Excessive lint can even bend metal parts, leading to major malfunctions. To clean your machine, first turn it off and unplug it. Remove the needle, presser foot, needle plate, and bobbin, then take out the shuttle hook where the bobbin sits.
Use a small brush, pipe cleaners, and tweezers to clean the bobbin area, under the bobbin holder, and around the feed dogs. These tools are perfect for removing both fine lint and larger debris.
"I was amazed the first time I opened my Bernina 801 (bought it used on eBay) how much lint a small space could hold. Lint was felted under and around the feed dogs." - CorgiNole, Super Member, Quiltingboard Forums
Avoid canned air when cleaning, as it can push lint deeper into your machine and potentially harm internal components. If your machine requires oiling, consult your owner's manual for guidance. Older mechanical models often need oiling more frequently, while newer computerized machines usually require professional lubrication once a year instead of at-home oiling.
Make it a habit to clean your machine regularly - ideally after every 2-3 bobbins of thread or at the end of each project. This simple maintenance will not only silence unusual noises but also help your machine last much longer. For additional maintenance tips, refer to your manual.
