Threading the bobbin on your Brother machine takes about two minutes once you know where the parts are
The bobbin is the small spool that holds thread underneath your fabric. To thread it, you wind thread onto an empty bobbin using your machine's bobbin winder, then place that loaded bobbin into the bobbin case. Most Brother machines have the bobbin winder on the top right of the machine, and the bobbin case sits inside the machine below the needle plate. The whole process—winding and inserting—takes less time than threading the top of the machine.
This guide covers the standard method for most Brother sewing machines, including the popular Brother CS6000i, Brother XM2701, and similar models. If your machine has a drop-in bobbin system (where the bobbin sits directly under the needle without a separate case), the winding step is the same, but insertion is simpler. Check your manual if you are unsure which system you have.
Key Takeaways
- Wind the bobbin first by placing an empty bobbin on the winder spindle, threading through the tension guide, and pressing the foot pedal or start button until the bobbin is full.
- Stop winding as soon as the bobbin is full—the machine will usually stop automatically, but if it does not, cut the thread and remove the bobbin by sliding it off the spindle.
- Insert the wound bobbin into the bobbin case by opening the case, placing the bobbin so the thread winds counterclockwise, and threading the thread through the tension spring.
- Close the bobbin case and slide it back into the machine until you hear or feel it click into place.
- The most common mistake is threading the bobbin thread through the tension spring backwards, which causes loose stitches on the underside of your fabric.
Locate the bobbin winder on top of your machine
Open the top of your Brother machine and look to the right side. You will see a metal spindle sticking up—this is the bobbin winder. Next to it is usually a small tension guide, which looks like a thin metal post or a notch in the plastic. Some Brother models have this guide built into the winder area itself.
Before you start, make sure you have an empty bobbin. Brother machines come with several plastic bobbins in the box. If you have lost yours, Brother bobbins are inexpensive and widely available. Do not try to use a bobbin from another brand—they may not fit properly and can jam the winder.
Wind thread onto the bobbin
Place an empty bobbin onto the winder spindle by sliding it straight down. It should sit flat and spin freely. Take the thread from your top spool (the one you would normally thread through the needle) and wrap it around the tension guide once or twice. Then thread it through the small hole in the side of the bobbin.
Hold the bobbin lightly with one finger to keep it from spinning, then press the foot pedal or press the start button on your machine. The bobbin will begin to wind. Keep light pressure on the thread with your other hand for the first few rotations to help it wind evenly. Once the bobbin is winding smoothly, you can let go.
The bobbin is full when it reaches the edge of the spindle and feels firm to the touch. Most Brother machines have an automatic stop—the winder will pause or the machine will beep when the bobbin is full. If your machine does not stop automatically, watch carefully and stop pressing the pedal as soon as the bobbin looks full. Overfilling can cause the bobbin to jam.
Cut the thread close to the bobbin and remove it by sliding it straight up and off the spindle. Set the full bobbin aside.
Open the bobbin case and prepare to insert the bobbin
Lower the presser foot (the metal piece that holds fabric down). This is important—on most Brother machines, lowering the presser foot opens the bobbin case latch. If your machine has a separate bobbin case door, open it now.
Look inside the machine below the needle. You will see a small metal or plastic case with a hinged door or a removable cover. This is the bobbin case. If it is hinged, gently pull it open. If it is removable, slide it out toward you. You should see a small metal spring inside the case—this is the tension spring, and it is critical to threading correctly.
Thread the bobbin through the tension spring
Hold the full bobbin so the thread comes off the top and winds counterclockwise (when you look at the bobbin from the side). This direction matters—if the thread comes off in the wrong direction, your stitches will be loose on the underside of your fabric.
Place the bobbin into the case so it sits flat in the center. Now take the thread end and slide it under the tension spring. The thread should pass under the spring from right to left, then come out on the left side. You will feel a slight resistance as the thread slides under the spring—that resistance is what creates the correct tension for your bobbin thread.
Leave about 4 to 6 inches of thread hanging out of the case. Do not pull the thread tight or wrap it around anything. Just let it hang loose.
Close the bobbin case and insert it into the machine
If your bobbin case is hinged, gently close the door until you hear a small click. If it is removable, slide it back into the machine from the front, pushing it straight in until it clicks into place. You should feel or hear a definite click—this means the case is locked and will not fall out during sewing.
Raise the presser foot. This closes the bobbin case latch on machines where the presser foot controls it. Your bobbin is now threaded and ready to use.
Common mistakes and how to avoid them
The most frequent error is threading the bobbin thread through the tension spring backwards. If you do this, the thread will not catch the spring properly, and your bottom stitches will be loose and loopy. The fix is straightforward: remove the bobbin case, rethread the bobbin thread under the spring in the correct direction (right to left), and reinsert the case.
Another common problem is overfilling the bobbin. If the bobbin is too full, it can jam inside the case or catch on the case door. Wind bobbins until they are level with the edge of the spindle, not beyond it. If a bobbin jams, stop when ready, remove the bobbin, and check for thread wrapped around the spindle.
Some people forget to lower the presser foot before opening the bobbin case. On most Brother machines, this can prevent the case from opening smoothly. Always lower the presser foot first, then open the case.
Frequently Asked Questions
What if my bobbin keeps coming loose during sewing?
The bobbin case is not clicking into place properly. Remove the case, make sure it is fully inserted and pushed all the way in, then listen for the click. If the case still feels loose, check that the presser foot is raised—on many Brother machines, the presser foot must be up for the case to lock. If the case is old or cracked, it may need to be replaced.
Can I use bobbins from other sewing machine brands?
No. Brother bobbins are sized and shaped specifically for Brother machines. Using a different brand's bobbin can cause it to jam, break, or damage the bobbin case. Brother bobbins are inexpensive and straightforward to find online or at fabric stores.
How do I know if the bobbin is wound in the right direction?
Hold the bobbin in your hand and look at it from the side. The thread should come off the top of the bobbin and wind counterclockwise as you look at it. If the thread comes off the bottom or winds clockwise, the bobbin was wound backwards. Unwind it and rewind it in the correct direction.
What if the bobbin winder will not stop when the bobbin is full?
Some older Brother models do not have an automatic stop. Watch the bobbin carefully as it fills. When it reaches the edge of the spindle and feels firm, stop pressing the foot pedal when ready. If you wait too long, the bobbin will overfill and jam. Cut the thread and remove the bobbin by hand.
Do I need to rewind the bobbin every time I change thread colors?
Yes. If you want a different color on the bottom of your fabric, you need to wind a new bobbin with that thread color. You can keep several bobbins wound with different colors and swap them out as needed, which saves time if you sew frequently.
