How Do You Put A Bobbin In A Sewing Machine

Overview of Bobbin Basics

Bobbins come in a variety of sizes and materials and are an essential part of any sewing machine. As the bobbin is used to store the bottom thread, it needs to be inserted into the machine correctly for the machine to work properly. To help ensure seamless sewing, it is important to know how to put a bobbin in correctly.

Types of Bobbin

The types of bobbin that are used vary depending on the make and model of the sewing machine. The most common types of bobbin are plastic, metal and pre-wound. Each of these types of bobbin has its own advantages and disadvantages and the type used will depend on the project being worked on.

Setup Process

Before the bobbin can be inserted, the machine must first be set up. This includes ensuring the machine is switched off, the presser foot is down, the stitch dial is in the zero position and the thread is threaded through the machine. Once these steps have been completed, the bobbin installation process can begin.

Inserting the Bobbin

The bobbin is inserted by placing it in the bobbin case and then making sure the case is held firmly in place. The bobbin case should align with the feed dog, which is the metal arch below the needle, and then the thread should be wound around the bobbin in a figure-eight shape. Once this is done, the bobbin should be inserted in the correct direction. This will vary depending on the make and model of sewing machine, but as a general rule, it should always be put in the same way it was taken out.

Tension Adjustment

After the bobbin has been inserted, it is important to adjust the tension on the bobbin case. This will depend on the type of fabric being sewn and the size of the thread being used, but as a rule, it is important to make sure the tension is not too tight or too loose. The tension should be tight enough to keep the thread from slipping, but loose enough so that the bobbin still turns freely.

Loading Bobbin Thread

Once the bobbin has been inserted and the tension is adjusted, it is time to load the bobbin thread. This is done by pulling the thread from the bobbin and wrapping it around the top threads, then pulling it up through the presser foot. Once this is done, the machine can be tested to ensure the bobbin thread has been loaded correctly.

Advantages of Learning Bobbin Basics

Learning the basics of how to put a bobbin in correctly can save time and frustration when sewing. There is nothing worse than having to constantly re-thread the machine because the bobbin has been inserted incorrectly. By knowing how to correctly insert a bobbin, it will save time and make sewing smoother.

How to Troubleshoot Bobbin Problems

If there are problems with the bobbin or it has been inserted incorrectly, there are some steps that can be taken to troubleshoot the problem. Firstly, it is important to check whether the bobbin has been threaded correctly and if it is in the right direction. If this has been done correctly, then it may be necessary to adjust the tension of the bobbin case. Finally, it is important to check if there is a build-up of lint on the moving parts as this may be preventing the bobbin from working correctly.

Common Mistakes When Inserting a Bobbin

One of the most common mistakes when inserting a bobbin is not inserting it in the right direction. This can lead to the thread getting tangled and the machine not working as it should. Another common mistake is not adjusting the bobbin case tension correctly. This can lead to too much slack in the thread, which can cause stitching problems.

Tips for Inserting a Bobbin Correctly

When inserting a bobbin the first time, it is important to take time and concentrate to ensure the bobbin is wound correctly and inserted correctly. This will give the best results and ensure the machine runs correctly. If the bobbin is being inserted for the second time, it is important to ensure the same tension is used as before to ensure the results are the same each time.


Knowing how to put a bobbin in correctly is an essential part of any sewing task. It is important to understand the different types of bobbin, the setup process, the correct way to insert the bobbin, how to adjust the tension and how to troubleshoot any problems that arise. With a bit of practice, inserting a bobbin correctly should be easy and will make sewing easier and more enjoyable.
