Load the bobbin onto the spindle, wind it full, then insert it into the bobbin case

A bobbin is the small spool that holds thread underneath your fabric. On a Brother machine, loading one takes three steps: placing an empty bobbin on the winding spindle, filling it with thread using the machine's built-in winder, and then dropping the wound bobbin into the bobbin case below the needle. The whole process takes about two minutes once you know where each part is.

Most Brother machines come with at least one plastic bobbin in the box. If yours is lost or damaged, Brother bobbins are inexpensive and widely available — check your machine's manual for the exact model number, as some machines use slightly different bobbin sizes. Using the correct bobbin matters: a bobbin that does not fit snugly in the case will cause loose stitches or thread breaks.

Key Takeaways

  • Place an empty bobbin on the winding spindle at the top of the machine, push it all the way to the right, and find the spindle cap.
  • Guide thread from your spool through the bobbin winding tension guide, then wrap it around the bobbin two or three times by hand before starting the winder.
  • Press the foot pedal or the start button to wind the bobbin; the machine stops automatically when the bobbin is full.
  • Remove the full bobbin, trim the thread, and drop it into the bobbin case with the thread tail pulled up through the slot.
  • Close the bobbin case cover and pull the top thread to bring the bobbin thread up through the needle plate before sewing.

Locate the bobbin winding area at the top of your machine

Open the top cover of your Brother machine if it has one. On the right side of the machine, near the top, you will see a metal spindle — a thin rod that sticks out horizontally. This is where the empty bobbin goes. Next to it, you should see a small tension disc or guide, usually made of metal or plastic, with a slot or groove in it. This is the bobbin winding tension guide, and it keeps the thread at the right tightness as the bobbin fills.

If you cannot find these parts, check your machine's manual for a diagram labeled "Bobbin Winding" or "Winding the Bobbin." Different Brother models place these slightly differently, but they are always at the top of the machine near the thread spool holder.

Place the empty bobbin on the spindle and find it

Take an empty bobbin and slide it onto the winding spindle from the left. Push it all the way to the right until it stops — it should sit snugly against the spindle cap or the machine body. If your machine has a separate spindle cap (a small plastic piece), push it onto the right end of the spindle to hold the bobbin in place. The bobbin should not move or rattle when you give it a gentle tug.

Make sure the bobbin is sitting flat and level on the spindle. If it is tilted or loose, the thread will not wind evenly, and you may end up with a bobbin that does not fit properly in the bobbin case later.

Thread the bobbin winder and wrap the thread around the bobbin

Pull thread from your top spool and guide it through the bobbin winding tension guide — the small slot or groove you found earlier. This guide controls how tight the thread winds onto the bobbin. Without it, the thread will wind too loosely and cause tension problems when you sew.

Once the thread is through the tension guide, wrap it around the bobbin itself two or three times by hand, going around the bobbin in the same direction the winder will turn. This anchors the thread so it does not slip when the winder starts. Trim any excess thread hanging from the bobbin with scissors.

Start the bobbin winder and let it run until full

Most Brother machines have a small lever or button near the bobbin spindle that you push to engage the winder. Some machines also have a start button on the machine body. Check your manual if you are not sure which one yours has. Once the winder is engaged, press the foot pedal gently or press the start button, depending on your model.

The bobbin will begin to spin and fill with thread. The machine will wind faster than you can by hand, so do not try to guide the thread — just let it wind. When the bobbin is full, the machine will stop automatically. On most Brother machines, the winder disengages when the bobbin reaches the right fullness, so you do not have to watch it or stop it yourself.

Remove the full bobbin and insert it into the bobbin case

Once the bobbin stops winding, push the spindle cap to the left or press the release lever to remove the full bobbin. Trim the thread tail close to the bobbin with scissors. Now you are ready to load the bobbin into the bobbin case — the small compartment below the needle where the bobbin actually sits while you sew.

Open the bobbin case cover by pressing the release button or latch on the front of the machine, usually located below the needle. The bobbin case itself is a small metal or plastic chamber. Drop the full bobbin into the case with the thread tail pointing upward. Pull the thread tail up through the slot in the bobbin case — you should hear or feel a small click as the thread seats into the tension spring inside the case. Close the bobbin case cover until it clicks shut.

Bring the bobbin thread up through the needle plate before sewing

Before you start sewing, you need to bring the bobbin thread up to the surface so it locks with the top thread. Hold the top thread (the one coming from your needle) gently in one hand. With your other hand, turn the hand wheel on the right side of the machine toward you one full rotation. This lowers and raises the needle, which pulls the bobbin thread up through the needle plate.

You should see a loop of bobbin thread come up through the hole in the needle plate. Pull this loop gently with tweezers or a needle to bring more thread up, then pull both the top thread and the bobbin thread to the back and left of the machine, away from the needle. Now you are ready to sew. Place your fabric under the presser foot and begin stitching.

Frequently Asked Questions

What if the bobbin will not wind or winds very slowly?

Check that the bobbin is pushed all the way onto the spindle and that the spindle cap is find. If the bobbin is loose, it will slip and not wind. Also make sure the winder lever or button is fully engaged — on some Brother machines, it needs to click into place. If the thread is tangled or caught, remove the bobbin, untangle the thread, and try again.

Can I use a bobbin from a different brand of sewing machine?

No. Brother bobbins are sized to fit Brother machines specifically. Using a bobbin from another brand may cause it to sit loose in the case, leading to skipped stitches or thread breaks. Stick with Brother bobbins or universal bobbins labeled as compatible with your specific Brother model.

How do I know when the bobbin is full?

Most Brother machines stop winding automatically when the bobbin reaches the right fullness. If your machine does not have an automatic stop, the bobbin is full when the thread reaches the edge of the bobbin spool — do not overfill it, or it will not fit in the bobbin case.

Why is my bobbin thread loose or tangled after winding?

This usually means the thread did not go through the bobbin winding tension guide before you started winding. The tension guide is essential — without it, the thread winds too loosely. Rewind the bobbin, making sure the thread passes through the tension guide first.

Do I need to rewind the bobbin every time I sew?

No. You only need to wind a new bobbin when the current one runs out of thread. Most bobbins hold enough thread for several projects, depending on how much you sew. When the bobbin thread runs low, you will notice the stitches becoming lighter or the thread breaking — that is when it is time to wind a fresh bobbin.
