Thread the bobbin in three steps
A bobbin is the small spool that holds the lower thread in your Brother sewing machine. To insert it, you lift the presser foot (the metal piece that holds fabric down), open the bobbin case cover on the front of the machine, drop the wound bobbin into the case with the thread end facing you, and close the cover. The whole process takes about 30 seconds once you know where everything is.
The bobbin case is the small compartment directly below where you insert the needle. On most Brother machines, you'll see a small latch or button on the front of the machine near the needle area. Push or slide this to open the cover and reveal the bobbin case underneath.
Before you insert a new bobbin, make sure the presser foot is in the up position. This opens a tension disc that would otherwise pinch the thread and prevent it from feeding correctly. If the presser foot is down, the bobbin thread won't move smoothly through the machine.
Key Takeaways
- Lift the presser foot before inserting the bobbin so the tension disc opens and allows thread to feed properly.
- Open the bobbin case cover by pushing or sliding the latch on the front of your machine, just below the needle area.
- Place the wound bobbin into the case with the thread end facing toward you, then close the cover until it clicks.
- Pull the bobbin thread up through the needle plate slot before you start sewing so both threads are ready to use.
Locate the bobbin case on your Brother machine
The bobbin case sits directly under the needle and presser foot. Look at the front of your machine, below the needle clamp. You'll see a small rectangular or oval cover plate. This is the bobbin case door. On most Brother models, including the Brother XM2701, Brother CS6000i, and Brother LX3817, the cover opens by pushing a small button or sliding a latch to the right or left.
If you're not sure which button opens it, check your machine's manual or look for any label printed on the machine itself. Some Brother models have a tiny arrow showing which direction to push. The cover should open easily without forcing—if it's stuck, you may be pushing the wrong button.
Once the cover is open, you'll see a metal or plastic bobbin case with a small slot or hook inside. This is where the bobbin sits. The case itself may be removable on some models, but on most modern Brother machines it stays in place and you straightforward drop the bobbin in from above.
Wind and insert the bobbin correctly
Before you can insert a bobbin, it needs to be wound with thread. Most Brother machines come with empty bobbins and a bobbin winding mechanism on the top or side of the machine. Wind the bobbin using your machine's winding feature until it's full, then cut the thread and remove the bobbin from the winder.
When you're ready to insert the wound bobbin, hold it so the thread end is facing toward you. Drop it gently into the bobbin case. The bobbin should sit flat in the case with the thread spool facing upward. You'll hear or feel a small click when it's seated correctly in some models.
Close the bobbin case cover by pushing or sliding the latch back into place. The cover should close smoothly and sit flush with the machine. If it doesn't close all the way, the bobbin may not be seated correctly—open the cover and try again.
Pull up the bobbin thread before sewing
After you close the bobbin case cover, you need to bring the bobbin thread up to the needle plate so both threads are ready to use. Hold the top thread (the one coming from the needle) gently in your hand. Turn the hand wheel on the right side of the machine toward you one full rotation. This moves the needle down and back up, which catches the bobbin thread and pulls it up through the needle plate.
Once the needle completes one full rotation, you should see a loop of bobbin thread coming up through the slot in the needle plate. Use a small tool like a seam ripper or tweezers to pull this loop up gently. You now have both the top thread and the bobbin thread ready above the needle plate.
Hold both threads to the back and left of the presser foot before you start sewing. This prevents the threads from tangling or pulling out of the needle as you begin. Once you've sewn a few stitches, the threads will stay in place on their own.
Troubleshoot common bobbin problems
If your machine is skipping stitches or the bobbin thread isn't feeding, the bobbin case cover may not be fully closed. Open it and check that the bobbin is sitting flat and centered in the case. A bobbin that's tilted or not fully seated will cause tension problems and uneven stitches.
If the bobbin thread keeps breaking, the bobbin case may have a rough spot or burr inside. Run your fingernail gently along the inside edges of the case. If you feel a rough area, you can sometimes smooth it with very fine sandpaper, but if the damage is deep, the case may need to be replaced. Contact Brother customer service or a local sewing machine repair shop for a replacement case.
If you're getting loops of bobbin thread on top of your fabric, the top thread tension is too loose. Check that the top thread is threaded correctly through all the guides and tension discs before adjusting the tension dial. Often the problem is a threading mistake, not the bobbin itself.
Know which bobbins work with your Brother machine
Brother machines use standard plastic bobbins that are the same size across most models. However, some older Brother machines and some specialty models use metal bobbins instead. Check your machine's manual to see which type yours uses. Using the wrong bobbin type can cause the machine to jam or skip stitches.
If you've lost your original bobbins, you can buy replacements at fabric stores, online retailers, or directly from Brother. Look for bobbins labeled as compatible with your specific machine model. A pack of 10 bobbins usually costs between $5 and $10. Keep a few wound bobbins on hand so you don't have to stop and wind a new one in the middle of a project.
Some Brother machines come with a bobbin case that's permanently attached, while others have a removable case. If your case is removable and you need to replace it, order the correct case for your model number. Installing a replacement case is the same process as inserting a bobbin—it drops into the machine from above and clicks into place.
Frequently Asked Questions
Which direction should the bobbin thread face when I insert it?
The thread end should face toward you, not away from you. This allows the thread to feed correctly through the tension mechanism inside the bobbin case. If the thread is facing the wrong way, the machine won't pick up the bobbin thread properly and you'll get loops or skipped stitches.
Do I need to thread the bobbin before inserting it?
No. The bobbin itself doesn't need to be threaded—it's already wound with thread. You only need to pull the bobbin thread up through the needle plate after you close the bobbin case cover. This brings the bobbin thread to the surface so it can work with the top thread.
What happens if the bobbin case cover doesn't close all the way?
The bobbin is probably not seated correctly in the case. Open the cover, remove the bobbin, and reinsert it, making sure it sits flat and centered. The cover should close smoothly without any resistance. If it still won't close, check that you're not inserting the bobbin upside down.
Can I use a bobbin from a different sewing machine brand?
Most standard plastic bobbins are compatible across Brother machines and many other brands, but some specialty machines use different sizes. Check your Brother manual to confirm the bobbin type. Using an incompatible bobbin can cause jamming or tension problems, so it's safer to use bobbins made for your specific machine.
How often do I need to replace the bobbin?
You don't replace the bobbin itself—you wind it with new thread when it runs out. A wound bobbin will last through many projects. If the bobbin cracks, warps, or develops rough spots, replace it with a new one. Most sewers keep several bobbins on hand so they can switch colors without rewinding.
