Thread the machine from the top down, then wind and insert the bobbin
Loading a sewing machine means two things: threading the needle with thread from the spool, and winding a separate bobbin with thread that sits underneath. Most machines have a marked path for the top thread — follow it exactly, because thread that skips a guide will break or skip stitches. The bobbin is simpler: wind it on a separate spindle, then drop it into the bobbin case below the needle plate.
The order matters. Always thread the needle first, then deal with the bobbin. If you do it backwards, the top thread can slip out of the tension discs while you are working below, and you will have to start over.
Key Takeaways
- Raise the presser foot before threading the needle, because this opens the tension discs and lets thread slip through.
- Follow the thread guides marked on your machine's body — each one is there to control tension, and skipping one causes thread breakage or loose stitches.
- Wind the bobbin on the machine's bobbin winder, not by hand, so the thread winds evenly and sits flat in the case.
- Insert the bobbin so the thread unwinds in the direction marked inside the bobbin case, usually counterclockwise.
- Pull both threads toward the back of the machine before you start sewing, so they do not tangle under the presser foot.
Raise the presser foot and prepare the machine
Before you thread anything, raise the presser foot — the hinged metal arm that holds fabric down. On most machines, a lever at the back lifts it. Raising the foot opens the tension discs inside the machine, which are two metal plates that grip the thread. If the foot is down, the discs are closed and thread cannot pass through them.
Place your spool of thread on the spool pin at the top of the machine. The pin usually stands upright on the left side, though some machines have a horizontal pin. Make sure the spool sits snugly and will not slip sideways as the thread unwinds.
Thread the needle following the marked path
Your machine has a threading path marked with numbers, arrows, or small metal guides. Start at the spool and follow this path exactly. The thread will pass through a tension dial (usually a round knob or slot), then through one or more guides, then through the needle bar, and finally through the needle eye itself.
Pull thread from the spool and guide it by hand through each point. Do not yank — let it sit in each guide for a moment so it settles. When you reach the needle, thread it from front to back (the direction the needle faces). Leave a tail of thread 4 to 6 inches long hanging below the needle.
If your machine has a needle threader — a small wire loop on the front — insert the loop through the needle eye, place thread in the loop, then pull the loop back out. This works on most machines and saves time, though it does not work on all needle sizes.
Wind the bobbin on the machine's winder
The bobbin is a small spool that holds thread underneath the needle. Wind it using the bobbin winder built into your machine, not by hand. Winding by hand creates uneven tension and the thread will not sit flat in the bobbin case.
Place an empty bobbin on the bobbin winder spindle — usually a small pin on the right side of the machine. Take thread from the main spool and wrap it around the bobbin two or three times by hand to anchor it. Then press the bobbin winder spindle toward the machine body (or flip a lever, depending on your model) to engage it.
Press the foot pedal or press a button to start winding. The bobbin will fill automatically. When it is full, the winder stops — most machines have an automatic cutoff. Remove the bobbin and trim the thread tail.
Insert the bobbin into the case
Open the bobbin case by lifting or sliding the needle plate — the metal plate directly under the needle. On some machines, the case is a removable metal or plastic unit; on others, it is built in. Look inside and you will see a small slot or hook where the bobbin sits.
Place the bobbin in the case so the thread unwinds in the direction marked inside — usually counterclockwise, though check your manual. The thread should pass under a small metal tension spring as it unwinds. Pull the thread so it sits under this spring; if it does not, the bobbin thread will be too loose.
Close the bobbin case and lower the needle plate back down. Make sure it clicks or locks into place.
Pull both threads to the back before sewing
Hold the top thread (the one coming from the needle) and turn the hand wheel toward you one full rotation. This brings the bobbin thread up through the needle plate. You will see a loop of bobbin thread appear.
Pull this loop gently with a needle or tweezers until the bobbin thread comes all the way up. Now you have both threads — top and bobbin — hanging below the needle. Pull both threads toward the back of the machine and hold them there while you position your fabric under the presser foot.
This step prevents thread tangles under the presser foot when you start sewing. It takes five seconds and saves you from having to pick apart a knotted mess later.
Troubleshoot if thread breaks or stitches skip
If thread breaks while you are sewing, the most common cause is that it skipped a guide during threading. Raise the presser foot, remove the thread, and rethread from the spool, making sure it passes through every marked point. Check that the needle is inserted correctly — the flat side of the needle should face the direction marked on your machine.
If stitches skip or look loose, the bobbin thread may not be sitting under the tension spring in the bobbin case. Remove the bobbin, check that the thread passes under the spring, and reinsert it. If the top thread looks loose, the presser foot may have been down when you threaded — raise it and rethread the needle.
If the needle keeps breaking, it may be bent or inserted backward. Replace it with a new needle of the correct size for your fabric, and make sure the flat side faces the right direction.
Frequently Asked Questions
Do I have to raise the presser foot before threading?
Yes. The presser foot controls the tension discs, and they must be open for thread to pass through. If you thread with the foot down, the thread will not sit in the discs correctly and will break or create loose stitches.
What if I cannot get the bobbin thread to come up through the needle plate?
Turn the hand wheel slowly toward you and watch the needle go down and come back up. The bobbin thread should loop up as the needle rises. If it does not, the bobbin may be inserted backward or the thread may not be under the tension spring. Remove the bobbin, check the direction, and try again.
Can I use the same bobbin over and over?
Yes. Bobbins are reusable — wind them as many times as you need. Replace a bobbin only if it cracks, warps, or has a rough edge that catches thread.
Why does my thread keep breaking?
Thread usually breaks because it skipped a guide during threading or the needle is bent or inserted backward. Rethread from the spool and follow every marked guide. If it still breaks, replace the needle with a fresh one in the correct size for your fabric.
What is the difference between top thread and bobbin thread?
Top thread comes from the spool and feeds through the needle. Bobbin thread sits underneath and creates the lock stitch with the top thread. You can use different colors — the top thread shows on top of the fabric, the bobbin thread shows on the back.
