Identify the tension screw: The bobbin case will have a small tension screw that can be adjusted to control the tension of the bobbin thread.
Test the tension: Insert a bobbin with thread into the bobbin case and hold the thread. Gently lift the bobbin case by the thread. The bobbin case should move slightly downward when released. If it drops too quickly or doesn’t move at all, it may need adjustment.
Adjust the tension screw: Use a small screwdriver to turn the tension screw clockwise to increase tension or counterclockwise to decrease tension. Make small adjustments and test the tension after each adjustment until the desired tension is achieved.
Reinstall the bobbin case: Once the tension is adjusted, place the bobbin case back into the machine and ensure it is properly inserted and secured.

Remember to refer to your sewing machine’s manual for specific instructions on adjusting bobbin tension, as the process may vary depending on the machine model.

Why is my sewing machine bunching up underneath?

If your sewing machine is creating a bunch of thread underneath the fabric, it is likely experiencing a problem called “bird nesting” or “thread bunching.” This issue can be caused by several factors:

Incorrect threading: Check that the upper thread is properly threaded through all the necessary guides and tension discs.
Bobbin issues: Ensure that the bobbin is inserted correctly and that the thread is wound evenly on the bobbin. Unevenly wound bobbins can cause thread to bunch up.
Tension problems: Improper tension settings can cause the thread to bunch up underneath the fabric. Check both the upper and bobbin tension and adjust as needed.
Needle problems: A bent or dull needle can cause the thread to snag or break, leading to thread bunching. Replace the needle if necessary.
Machine maintenance: Regularly clean and oil your sewing machine to prevent lint or debris from interfering with the thread’s path.

By addressing these potential issues, you should be able to resolve the problem of thread bunching up underneath the fabric and achieve smooth, even stitches.

To determine if your thread tension is correct, you can perform a simple test. Take two different colored threads and sew a few stitches on a scrap piece of fabric. Examine the stitches on both sides of the fabric. If the top thread is pulling through to the bottom side of the fabric, the tension is too loose. If the bottom thread is pulling through to the top side of the fabric, the tension is too tight. Ideally, the stitches should be balanced, with the top and bottom threads meeting in the middle of the fabric. Adjust the tension dial accordingly to achieve balanced stitches.

What is the higher number the higher the tension on a sewing machine?

On most sewing machines, the higher the number on the tension dial, the higher the tension on the thread. Increasing the tension can be useful when sewing heavier fabrics or when you want to create tighter stitches. However, it is important to find the right balance for your specific project and fabric. Experiment with different tension settings and perform test stitches to achieve the desired results.

When should I change my sewing tension?

You may need to change your sewing tension when you switch to a different fabric or thread type. Different fabrics and threads require different tension settings to achieve optimal stitch quality. For example, if you are sewing a lightweight fabric, you may need to decrease the tension to prevent the fabric from puckering. On the other hand, if you are sewing a heavy fabric, you may need to increase the tension to ensure the stitches are secure. Additionally, if you notice any issues with your stitches, such as loops or uneven tension, adjusting the tension can help resolve these issues.

Summary

When the bottom string on a sewing machine is loose, it could be due to incorrect bobbin insertion or tension settings. Bunching up and breaking of thread can be caused by tight tension, incorrect threading, or using the wrong needle size. To fix bobbin thread bunching, ensure correct insertion and evenly wound thread. To check thread tension, perform a test stitch with different colored threads. Higher numbers on the tension dial indicate higher tension. Change sewing tension when switching fabrics or threads or when experiencing stitch issues. Adjusting tension can help achieve balanced stitches and prevent thread breakage.
