How To Put The Bottom Bobbin In A Sewing Machine

The Basics of the Bottom Bobbin

To get the best out of your sewing machine, you’ll need to understand how to put the bottom bobbin in the right places, and what it does. Sewing machines use two types of thread: the top thread, which is the visible one that creates the seam or stitch, and the bottom thread, or bobbin thread, which is hidden from view. The bobbin is encased in a plastic or metal case known as a bobbin case. This holds the thread in place and makes sure that the top thread and bobbin thread form a neat loop and virtually invisible stitch.

Usually, the bobbins are in two parts: the bobbin case, which is where the bobbin thread is wound, and the bobbin, which is the thread that actually creates the loops. It’s the tension between the two threads in the bobbin that ensures a uniform and neat, invisible seam. If the bobbin is too loose or the tension is uneven, it can lead to a messy stitch.

What You Need

To get started, you’ll need a bobbin for your sewing machine. You can purchase bobbins in a variety of sizes depending on the type of machine you have and the type of fabric you’ll be working with. You’ll also need a bobbin case, which should come with your machine. Check the manual for the correct type of bobbin for your machine.

Once you have your bobbin and bobbin case, it’s time to get started. Make sure you’re familiar with the various parts of your machine, and that you know where the bobbin case is located. Some sewing machines have the bobbin case located underneath the needle, while others may be located in the top portion of the machine.

How to Put in the Bottom Bobbin

Once you’re familiar with your machine, the process of putting in the bobbin is straightforward. Begin by winding the thread onto the bobbin, making sure you don’t have any kinks or knots in the thread. Place the bobbin onto the bobbin case and insert it into the machine. Feed the top thread into the tension disc and make sure it lines up with the eye of the needle.

Now it’s time to actually feed the bobbin into the machine. Depending on your machine, you may have to manually draw the top thread up through the tension disk before you can feed it into the machine. To do this, turn the handwheel of the sewing machine until you can see the needle move up and down. Keep a firm grip on the thread to keep it taut, and then slowly turn the handwheel in the opposite direction until the needle moves up again.

Once the top thread is in place, you can begin to thread the bottom thread into the machine. Make sure you keep a firm grip on the bobbin case and then lower it into the machine. When it’s in the correct position, you should be able to see the slit in the bobbin case that’s designed to hold the bobbin thread. Push the thread through this slit and then slowly lower the bobbin case back into the machine.

The Finishing Touches

When the bobbin is securely in place, it’s time to start stitching. Start by pulling the top thread to the back of the machine, and then lightly tug on the bobbin thread. You’ll need to keep a steady grip on both the top and bottom threads, and then turn the handwheel until you can see a small loop of thread form at the back of the machine. Once you have the loop, you can continue to stitch as normal.

The key to successful bobbin insertion is to make sure both the top and bottom threads flow freely and evenly, and that the tension between the two threads is consistent. If everything is in the right place and working in harmony, your stitches should be uniform and neat.


If you’re having problems with your bobbin, the first step is to determine whether the bobbin is in the correct position. Make sure the slot in the bobbin case is facing up and that the bobbin is properly aligned with the needle. Sometimes slight adjustments are needed to get everything in the right place. You can also check the machine’s tension controls to make sure the tension between the top and bottom threads is correct.

If you’re still having trouble getting the bobbin to stay in place, it could be due to worn parts or bobbins. If the bobbin case is worn, the bobbin may fall out. In this case, you’ll need to replace the bobbin case. And if the bobbin is old, it may be frayed or weak and need to be replaced. If a new bobbin doesn’t solve the problem, it’s time to take it to a professional.

Maintenance and Replacement

Regular maintenance is always recommended when using a sewing machine. This involves cleaning and lubricating the bobbin case, the needle, and all of the machine’s parts. The bobbin case should be cleaned and inspected regularly to make sure it’s free from dirt and dust. When the bobbin case is starting to show signs of wear, you should replace it with a new one as soon as possible.

Be sure to replace any worn or broken bobbins as soon as you can so you don’t end up with a dissatisfying stitch. Over time, bobbins can become frayed or weak, resulting in uneven stitches or skipped loops. Keep a few extra bobbins on hand so you can quickly switch out the old ones.

Alternative Threading Patterns

If you’re looking to add a unique style to your sewing projects, you can try alternative bobbin threading patterns. This involves threading the top and bottom threads in different ways to create more intricate and decorative stitches. Some machines have settings to enable you to thread the bobbin differently, while others may require you to manually thread it. With practice and a bit of patience, you can create stunning patterns!

Common Mistakes

When inserting a bottom bobbin, it’s important to be aware of common mistakes that could lead to an unsatisfactory stitch. Insufficient tension between the top and bottom threads can cause uneven stitches. And if the bobbin isn’t in the correct position in the bobbin case, the thread may not feed correctly and you’ll end up with a broken stitch.

Be sure to inspect the bobbin case regularly for signs of wear or damage. The machine’s tension should also be checked periodically to ensure it’s set correctly. And if you’re still having problems with your bobbin, take it to a professional to ensure it’s working correctly.

Target Audiences

Knowing how to put in the bottom bobbin is an essential skill for beginner sewers, as well as experienced ones. Beginners should familiarize themselves with their sewing machine and understand the basics of bottom bobbin insertion before attempting to thread it. And experienced sewers should take the time to regularly inspect their bobbin case and bobbins to ensure they’re in good condition.

Threading a bobbin can be a daunting task, especially for beginners. But with the right tools and information, anyone can learn to thread a bobbin like a pro. With regular practice and maintenance, you should be able to get great results every time!
