Learning how to put thread in a sewing machine is a fundamental skill for any sewer. Whether you are a beginner or have been sewing for a while, getting the threading right ensures smooth stitching and prevents frustration. So, how do you thread a sewing machine? Generally, you start by placing the spool of thread on the spool pin, then follow a specific path through guides, tension discs, and finally the needle eye, before bringing the bobbin thread up. This guide will break down the process into simple, manageable steps.
Sewing machines, marvels of mechanical engineering, bring fabric to life stitch by stitch. But before you can create beautiful garments or mend torn clothes, you need to get the thread in the right place. This involves two main components: the upper thread and the bobbin. Mastering the threading needle and the bobbin winding process is key to unlocking your sewing machine’s potential. Let’s dive into the art of threading your machine, from setting up the spool to inserting bobbin and achieving perfect stitches.

Preparing Your Sewing Machine for Threading
Before you begin threading, take a moment to prepare your machine. This ensures a clean and efficient start.
What You’ll Need
- Sewing Machine Manual: Every machine is a little different. Your manual is your best friend for specific threading paths.
- Spool of Thread: Choose good quality thread that matches your fabric.
- Bobbin: Make sure it’s the correct type for your machine.
- Sewing Machine: Of course!
- Scissors or Thread Cutter: To snip the thread.
General Machine Setup
- Turn off the Machine: Always turn off your sewing machine before threading. This prevents accidental starts and potential injury.
- Raise the Presser Foot: Lift the presser foot lever. This opens the thread tension discs, allowing the thread to pass through smoothly.
- Lower the Needle: Turn the handwheel towards you to lower the needle. Then, turn it again to raise the needle back to its highest position. This ensures the needle bar is in the correct place for threading.
Threading the Upper Thread
The upper thread is the main thread that comes from the spool. Following the correct path is crucial for good stitches.
Step 1: Placing the Spool
- Locate the spool pin on your machine. It’s usually on the top or back.
- Place your spool of thread onto the spool pin. Make sure the thread unwinds from the spool in the direction recommended by your manual (usually from the top or the back).
- If your machine has a spool cap, place it on the spool to keep it from unwrapping too much.
Step 2: Following the Thread Path
Every sewing machine has a numbered or diagrammed thread path printed on its body. This is your guide!
- Thread Guide: Start by passing the thread through the first thread guide, usually a small metal or plastic loop near the spool pin.
- Take-Up Lever: Guide the thread down towards the take-up lever. This is a metal arm that moves up and down with the needle. Thread the upper thread through the eye or slot in the take-up lever. Ensure it passes from right to left or left to right as indicated by your machine.
- Tension Discs: Now, bring the thread down to the thread tension discs. This is where the magic of stitch control happens. The thread should go between these two discs. Make sure the thread is seated correctly in the groove of the top disc.
- Thread Guide Below Tension: Continue to follow the path downwards. You’ll find more thread guides. Pass the thread through them in the order shown on your machine.
- Around the Feed Dog Guard (if applicable): Some machines have a guard for the feed dogs. Guide the thread around this if your machine has one.
- Needle Clamp Thread Guide: You’ll find a small thread guide near the needle clamp. Pass the thread through this.
Step 3: Threading the Needle
This is often the trickiest part, but with practice, it becomes second nature.
- Needle Position: Ensure the needle is in its highest position.
- Needle Eye: Bring the thread towards the needle.
- Manual Threading: For most machines, you’ll guide the thread through the eye of the needle from front to back.
- Automatic Needle Threader (if available): Many modern machines have an automatic needle threader.
- Make sure the needle is in its highest position.
- Bring the thread in front of the needle, aligning it with the threader’s hook.
- Push the threader lever down. The hook will catch the thread and pull a loop through the needle’s eye.
- Gently pull the loop of thread through.
- Leave a Tail: Once threaded, leave a tail of about 4-6 inches of thread hanging from the needle. This is important for pulling up the bobbin thread.
Winding the Bobbin
A properly wound bobbin is essential for balanced stitches. The process of bobbin winding is separate from threading the needle.
Step 1: Preparing the Bobbin
- Select a bobbin that is compatible with your sewing machine.
- Place the bobbin onto the bobbin winding spindle. This spindle is usually a small peg on top of your machine, often near the spool pin. It might be spring-loaded.
Step 2: Starting the Bobbin Thread
- Take your spool of thread and place it on the spool pin, just as you did for the upper thread.
- Guide the end of the thread through the small hole in the bobbin.
- Hold the end of the thread firmly against the bobbin.
- Gently push the bobbin winding spindle to the side, engaging the winding mechanism. Your machine might have a clutch that disengages the needle.
Step 3: Winding the Bobbin
- Begin Winding: Slowly turn the handwheel towards you to start winding the thread onto the bobbin. Make sure the thread goes evenly around the bobbin.
- Cut the Tail: Once you have a few wraps of thread, snip the tail end that you were holding. This prevents it from getting caught.
- Continue Winding: Let the machine wind the bobbin. Keep an eye on the thread as it winds. It should fill the bobbin evenly, without overlapping too much or being too loose.
- Stopping: Most machines have an automatic stop when the bobbin is full. If yours doesn’t, stop winding when the thread reaches about 1/4 inch from the top of the bobbin.
- Finishing: Once wound, push the bobbin spindle back to its original position. Cut the thread from the spool. Remove the wound bobbin.
What is bobbin winding?
Bobbin winding is the process of filling an empty bobbin with thread from a spool. This wound bobbin provides the lower thread for your sewing machine.
Inserting the Bobbin
Now that you have a wound bobbin, it’s time to put it into the bobbin case or shuttle.
Types of Bobbin Cases
There are two main types of bobbin systems:
- Front-Loading (Drop-in Bobbin): The bobbin is inserted into a bobbin case located under the needle plate. This is common on many modern machines.
- Top-Loading (Front-Loading): The bobbin is inserted into a removable bobbin case that then fits into a shuttle hook at the front or side of the machine. This is common on older or more basic machines.
Step 1: Preparing the Bobbin Area
- Remove the Needle Plate/Cover: If you have a front-loading bobbin, you’ll need to remove the needle plate or cover to access the bobbin area.
- Remove the Bobbin Case (if applicable): If your machine has a removable bobbin case, take it out.
Step 2: Inserting the Bobbin
The direction of the thread unwinding from the bobbin is crucial for correct stitching.
For Front-Loading (Drop-in Bobbin) Machines:
- Place the Bobbin: Place the wound bobbin into the bobbin holder. The thread should unwind from the bobbin in a counter-clockwise direction. (Check your manual, as some machines differ.)
- Follow the Thread Guide: You’ll see a small groove or slot on the bobbin holder and the bobbin itself. Guide the thread into this groove.
- Pull the Thread: Pull the thread through the small slit at the end of the bobbin holder to secure it.
- Replace the Cover: Put the needle plate or cover back on.
For Top-Loading (Removable Bobbin Case) Machines:
- Place the Bobbin: Place the wound bobbin into the bobbin case. The thread should unwind from the bobbin in a clockwise direction. (Again, consult your manual for specific directions.)
- Thread the Case: Guide the thread through the small slit in the side of the bobbin case, and then through the tension spring.
- Insert the Case: Hold the bobbin case by the small finger-like projection. With the thread coming from the top of the bobbin case, insert it into the shuttle hook. The thread should be coming from the left side of the case.
- Check the Fit: The bobbin case should fit snugly into the shuttle.
What is inserting bobbin?
Inserting bobbin is the action of placing the wound bobbin into its designated holder within the sewing machine, ensuring the thread unwinds correctly for stitching.
Bringing Up the Bobbin Thread (Threading the Shuttle)
After threading the upper thread and inserting bobbin, you need to bring the bobbin thread up to meet the upper thread. This step is sometimes referred to as threading shuttle when referring to older machines.
- Hold the Upper Thread: With one hand, gently hold the tail of the upper thread.
- Turn the Handwheel: Slowly turn the handwheel towards you. This will lower the needle, catch the bobbin thread, and pull a loop of it up through the needle plate.
- Catch the Loop: As the needle comes back up, a loop of bobbin thread will appear in the needle plate opening.
- Pull Up the Bobbin Thread: Use your fingers or tweezers to catch this loop and pull it completely through the needle plate. You should now have both the upper thread and the bobbin thread in front of the needle.
- Position the Threads: Place both thread tails behind the presser foot and under the presser foot. Leave a few inches of both threads trailing.
What is threading shuttle?
Threading shuttle typically refers to the process of preparing and inserting the bobbin into its housing within the sewing machine, especially in machines with a removable shuttle or bobbin case.
Checking Your Threading
Before you start sewing, a quick check ensures everything is correctly in place.
- Thread Path: Double-check that the thread follows all the guides, discs, and the take-up lever correctly.
- Needle Threading: Ensure the thread is securely through the needle’s eye.
- Bobbin Insertion: Confirm the bobbin is in correctly and the thread is pulled up.
- Tension: The thread tension is key. When you gently pull on both the upper thread and the bobbin thread, they should feel balanced. You shouldn’t be able to pull one much easier than the other.
Troubleshooting Common Threading Problems
Even experienced sewers encounter threading issues. Here are some common problems and solutions:
| Problem | Cause | Solution |
|---|---|---|
| Skipped Stitches | Needle is bent or dull. | Replace the needle. Ensure it’s inserted correctly and to the proper height. |
| Thread is not correctly threaded through the machine. | Re-thread the entire machine, paying close attention to the upper thread path and the bobbin winding. | |
| Thread tension is too loose. | Adjust the thread tension dial, usually increasing it for the upper thread. | |
| Thread Breaking | Thread is knotted or snagged. | Use a new section of thread or a new spool. Ensure the thread path is clear. |
| Needle is inserted incorrectly (e.g., wrong side facing forward). | Re-insert the needle, ensuring the flat side faces the back. | |
| Thread tension is too tight. | Reduce the thread tension on the upper thread. | |
| Needle eye is too small for the thread. | Use a larger needle or thinner thread. | |
| Bobbin is wound unevenly or improperly inserted. | Rewind the bobbin, ensuring smooth bobbin winding. Check inserting bobbin for the correct direction. | |
| Bird’s Nesting (Thread Bunching) | Machine is not threaded correctly. | Re-thread the upper thread completely, making sure the presser foot is up when threading. Ensure the thread is correctly seated in the thread tension discs. |
| Thread tension is too loose. | Increase thread tension on the upper thread. | |
| Bobbin thread is not pulled up correctly. | Re-do the step to bring the bobbin thread up. | |
| Bobbin is not inserted properly into the bobbin case. | Remove the bobbin and re-insert it according to the correct direction and ensuring the thread goes through the slit. | |
| Uneven Stitches | Thread tension is not balanced between upper and bobbin threads. | Adjust the thread tension for either the upper thread or the bobbin. (Some machines have bobbin tension adjustment, but often it’s best left to a professional). |
| Needle is bent or worn. | Replace the needle. | |
| Lint build-up in the bobbin area or tension discs. | Clean your sewing machine, especially the bobbin area and around the thread tension discs. |
How do I know if my thread tension is correct?
The thread tension is correct when the stitches are balanced on both sides of the fabric. If the upper thread is breaking or making loops on the underside, the tension is too high. If the bobbin thread is showing on the top side and making loops, the tension is too low. A good test is to sew a few stitches on a scrap piece of your fabric and check the stitch quality.
Frequently Asked Questions (FAQ)
Q1: What if my sewing machine doesn’t have numbers for threading?
A1: Most sewing machines have diagrams printed on the machine body that show the thread path. If yours doesn’t, consult your machine’s manual. It will provide a detailed diagram and step-by-step instructions for threading needle and setting up the bobbin.
Q2: Can I use any thread with my sewing machine?
A2: While you can technically use many types of thread, it’s best to use good quality polyester or cotton thread suitable for your fabric type and machine. Very thick, thin, or specialty threads might require different needles or thread tension adjustments and can sometimes cause issues if not used carefully. Always check your manual for thread recommendations.
Q3: My machine is making a loud noise or skipping stitches, what could be wrong?
A3: This often points to a threading issue. Double-check that you have threaded the upper thread correctly, that the presser foot is down, and that the bobbin is inserted properly and the thread is pulled up. Lint build-up in the bobbin area or around the thread tension discs can also cause problems. Clean your machine regularly.
Q4: How often should I re-thread my sewing machine?
A4: You should re-thread the upper thread every time you change the spool of thread or the type of stitch you are sewing. The bobbin should be rewound when it runs out of thread. It’s also a good practice to re-thread the machine if you encounter stitch problems, as incorrect threading is a common cause.
Q5: What is the purpose of the bobbin?
A5: The bobbin holds the lower thread that is used to create stitches. It works in conjunction with the upper thread to form a complete stitch by interlocking the two threads. Without a properly wound and inserted bobbin, the sewing machine cannot sew.
Q6: My bobbin thread keeps tangling at the start of my sewing. What am I doing wrong?
A6: This usually means the upper thread is not properly seated in the thread tension discs or the take-up lever, or the bobbin thread wasn’t pulled up correctly. Make sure you’ve re-threaded the upper thread with the presser foot UP. Also, ensure the bobbin thread loop was fully pulled up before you started sewing.
By following these detailed steps and tips, you’ll become proficient at threading your sewing machine, setting you up for successful and enjoyable sewing projects. Happy sewing!
