Before you begin sewing your next project, it’s important to make sure your sewing machine is properly threaded. Improper threading can lead to a variety of problems, including skipped stitches, broken thread, and even damage to your machine. One of the most important steps in the threading process is threading the bobbin. If the bobbin is not threaded correctly, you will not be able to sew properly.
The first step is to wind the thread onto the bobbin. Hold the bobbin in one hand and thread the end of the thread through the hole in the side of the bobbin. Wrap the thread around the bobbin a few times, then place the bobbin on the winding spindle and start winding. When the bobbin is full, cut the thread and remove the bobbin from the winding spindle.
Next, you need to insert the bobbin into the bobbin case. The bobbin case is usually located on the underside of the sewing machine. Open the bobbin case and place the bobbin inside. Make sure that the thread is coming off of the bobbin in the correct direction. Close the bobbin case and pull the thread through the small hole in the side of the case.
Inserting the Bobbin into the Machine
**Step 1: Locate the Bobbin Area**
Identify the bobbin area on your machine, typically located beneath the needle plate or behind a small cover. It may have a diagram indicating the proper direction for bobbin insertion.
**Step 2: Insert the Bobbin Case**
Open the bobbin door or cover and place the bobbin case inside. Make sure that the arrow or indentation on the bobbin case aligns with the corresponding markings on the machine.
**Step 3: Place the Bobbin on the Bobbin Case**
Hold the bobbin so that the thread is unwinding in a clockwise direction (if viewed from above). Place the bobbin on the bobbin case and ensure it is snugly seated.
**Step 4: Thread the Bobbin**
Locate the thread guide on the bobbin case. Guide the thread around the thread guide and through the tension disc. Make sure the thread passes smoothly through both guides.
**Step 5: Secure the Thread End**
Cut a small piece of thread from the bobbin and thread it back through the hole in the bobbin case. This will secure the thread and prevent it from unwinding while sewing.
**Step 6: Close the Bobbin Door**
Carefully close the bobbin door or cover. Ensure it is securely latched to prevent the thread from tangling or snagging.
| Tip |
|---|
| Use a new, clean bobbin for each project to avoid thread jams or breaks. |
| If the bobbin thread is too loose, it may cause puckering or skipped stitches. If it is too tight, it may cause thread breakage. |
| Consult your sewing machine manual for specific instructions on bobbin insertion and threading, as different machines may have variations. |
Guiding the Thread through the Tension Disc
After passing through the thread guide, the thread now needs to be guided through the tension disc. The tension disc is a small, round disc that is located near the bobbin winder. Its purpose is to provide just the right amount of tension on the thread so that it can be evenly wound onto the bobbin.
To guide the thread through the tension disc, first locate the small hole in the center of the disc. Then, take the thread and pass it through the hole from the front of the machine to the back. Be sure to pull the thread all the way through the hole so that it is taut.
Once the thread is through the hole, it will need to be wrapped around the tension disc. To do this, simply take the thread and wrap it around the disc once in a clockwise direction. Then, pull the thread back up through the hole in the disc so that it is now on the front of the machine.
Alternative Methods for Guiding Thread through Tension Disc:
| Method | Description |
|---|---|
| Standard Method | Pass the thread through the hole in the tension disc from front to back. |
| Underneath Method | Pass the thread underneath the tension disc, then up through the hole. |
| Over-the-Top Method | Pass the thread over the top of the tension disc, then down through the hole. |
Experiment with different methods to determine which one works best for your particular machine and thread type.
Winding the Thread onto the Bobbin
Before you can thread your sewing machine, you need to wind the thread onto the bobbin. This is a simple process, but it’s important to do it correctly to avoid tangles and other problems.
Here are the steps on how to wind the thread onto the bobbin:
- Place the empty bobbin on the bobbin winder.
- Feed the end of the thread through the tension disc and into the bobbin.
- Turn on the bobbin winder and hold the loose end of the thread until it starts to wind.
- Once the thread is winding smoothly, let go of the loose end and continue winding until the bobbin is full.
Additional details for step 4:
As you wind the thread onto the bobbin, be sure to keep the thread tight. If the thread is too loose, it will tangle and cause problems. You can also use a bobbin winder to help keep the thread tight.
Once the bobbin is full, cut the thread and remove it from the bobbin winder.
| Troubleshooting tips |
|---|
| If the thread is tangling, try winding it more slowly. |
| If the thread is breaking, try using a different type of thread or adjusting the tension. |
Inserting the Bobbin into the Bobbin Case
Inserting the bobbin into the bobbin case correctly is crucial for the proper functioning of your sewing machine. Here is a detailed step-by-step guide to ensure you do it accurately:
1. Prepare the Bobbin
Start by winding the thread onto the bobbin using a bobbin winder or by hand. Make sure the thread is wound evenly and tightly to avoid tangling.
2. Locate the Bobbin Case
Identify the bobbin case on your sewing machine. It is typically a small, hollow compartment located under the needle plate.
3. Access the Compartment
Slide the bobbin case latch or press the release button to open the compartment. The compartment should swing out or slide open, revealing the bobbin case inside.
4. Insert the Bobbin
Place the wound bobbin into the bobbin case. Ensure that the thread coming off the bobbin is facing you. Gently push the bobbin in until it clicks or locks into place.
5. Wind the Thread
After inserting the bobbin, you need to wind the thread around the bobbin winder spring or tension disc. Here’s a detailed explanation:
| Step | Description |
|---|---|
| a. | Identify the bobbin winder spring or tension disc. It is usually located on the side of the bobbin case. |
| b. | Take the thread coming off the bobbin and wrap it around the spring or tension disc in a clockwise direction. |
| c. | Wrap the thread around the spring or tension disc 2-3 times to create tension and prevent the thread from slipping. |
| d. | Pull the thread until you feel slight resistance, indicating that the bobbin is properly tensioned. |
Pulling the Thread through the Needle Eye
Threading the needle eye can be tricky, especially with smaller needles. Here’s a detailed guide to ensure success:
Step 1: Cut the Thread End
Before threading, cut a fresh end of thread to eliminate any loose fibers that could hinder threading.
Step 2: Dampen the Thread
Slightly dampen the cut thread end with water or saliva. This helps stiffen the thread, making it easier to guide through the eye.
Step 3: Thread the Needle
Hold the needle firmly and insert the thread end into the eye. Slowly and gently guide the thread through until it emerges on the other side.
Step 4: Push the Thread Through
Use a needle threader or tweezers to gently push the thread the rest of the way through. Avoid pulling, as this can damage the thread or the needle.
Step 5: Double-Check
Pull on the thread to ensure it is securely threaded through the eye. The thread should not slack or hang loosely.
Step 6: Fine-Tuning
If the thread is pulling from the eye too easily, adjust the tension by slightly tightening the thread tension screw or dial on the machine.
| Needle Size | Approximate Screw Tightness |
|---|---|
| #10 – #12 | Slightly tighter than hand tighten |
| #14 – #16 | Hand tighten |
| #18 – #20 | Slightly looser than hand tighten |
If the thread is not pulling at all, loosen the tension slightly to allow for smoother movement.
Knotting the Two Threads Together
Now that you have threaded both the needle and bobbin, it’s time to knot the two threads together. This will ensure that the threads are securely connected and will prevent them from coming undone while you’re sewing.
- Bring the needle and bobbin threads up to the top of the sewing machine, leaving a few inches of thread hanging from each one.
- Form a small loop with the needle thread and hook it onto the tip of the bobbin thread.
- Wrap the bobbin thread around the needle loop twice, then pull the two ends of the bobbin thread taut.
- Pull the needle thread through the loop you created in Step 2.
- Tighten the knot by pulling on both ends of the thread.
- Trim any excess thread.
Here’s a more detailed explanation of the knotting process, with diagrams:

Adjusting the Tension for Optimal Stitching
Inspecting the Bobbin Tension
To evaluate the tension of the bobbin thread, hold the wound bobbin between your fingers, allowing a few inches of thread to hang loose. Gently pull on the loose end. If the tension is correct, the thread should exhibit some resistance but should not snap or pull out easily.
Adjusting the Tension
On most sewing machines, the bobbin tension is adjustable via a screw or dial located near the bobbin case. Typically, tightening the screw or turning the dial clockwise increases the tension, while loosening the screw or turning the dial counterclockwise decreases it.
| Level | Suitable for: |
|---|---|
| Loose Tension | Thin, delicate fabrics |
| Medium Tension | General-purpose fabrics |
| Tight Tension | Heavy-duty fabrics |
Checking the Tension Output
To check the tension output, insert both the top and bobbin threads into the machine and sew a few test stitches on a scrap of fabric. Examine the stitches carefully. If the top thread is pulling up the bobbin thread, increase the bobbin tension. If the bobbin thread is pulling up the top thread, decrease the bobbin tension.
By following these steps and adjusting the tension appropriately, you can ensure optimal stitching results on your sewing machine.
Troubleshooting Threading Issues
If you’re having trouble threading your bobbin, here are some common issues and how to fix them:
1. The thread is too loose or too tight
If the thread is too loose, it may not catch on the bobbin correctly. If it’s too tight, it may break or cause the bobbin to jam. Adjust the thread tension until it’s just right.
2. The bobbin is not wound evenly
If the bobbin is not wound evenly, the thread may not feed properly. Rewind the bobbin carefully, making sure the thread is wound in an even layer.
3. The bobbin case is not inserted correctly
If the bobbin case is not inserted correctly, the thread may not be able to reach the needle. Make sure the bobbin case is inserted all the way into the machine and that the thread is pulled through the slot.
4. The needle is bent or damaged
If the needle is bent or damaged, it may not be able to pick up the thread from the bobbin. Replace the needle with a new one.
5. The needle threader is not working properly
If the needle threader is not working properly, it may not be able to guide the thread through the needle. Clean or replace the needle threader, and make sure it’s properly attached to the machine.
6. The thread is knotted
If the thread is knotted, it may not be able to pass through the needle or the bobbin. Cut off the knot and rethread the machine.
7. The fabric is too thick
If the fabric is too thick, it may not be able to feed through the machine properly. Use a thinner fabric or adjust the presser foot pressure.
8. The machine is not oiled
If the machine is not oiled, it may not be able to run smoothly. Oil the machine according to the manufacturer’s instructions.
9. Other issues
If you’ve tried all of the above troubleshooting tips and you’re still having trouble threading your bobbin, there may be a problem with your machine. Consult your machine’s manual or take it to a qualified repair technician.
