How To Thread A White Rotary Sewing Machine

Threading the Machine

Threading a white rotary sewing machine is an important part of prepping to sew. It can seem intimidating at first, but once you understand the basics of what you need to do, it’s a fairly straightforward process. In this article, we’ll explain the basics of how to thread your white rotary machine.
The first thing you’ll need to do is make sure that you have the correct thread for your machine. Different types of fabric require different thread, so it’s important to check the specifications of your machine before you thread it. Generally, if you’re using a white rotary machine, you’ll want to use a medium-weight, standard-sized cotton thread.
Once you have the right thread, the next step is to thread the top of the machine. To do this, begin by finding the spool pin above the needle. This is a small metal pin that slides between the needle and the bobbin case. Attach the top spool of thread to the spool pin. If your machine has a thread guide, you’ll need to use that as well.
After the top of the machine is threaded, the next step is threading the bottom. You’ll need to remove the bobbin case, which is located at the bottom of the machine. Once the bobbin case is removed, you’ll need to wind the thread around the bobbin. To ensure that the thread is wound correctly, you should wind it in one direction, following the arrows and not crossing the thread over itself. Once the bobbin is wound, you can replace the bobbin case.
Once the machine is threaded, you’ll need to make sure that everything is correctly in place. Begin by inserting the bobbin into the bobbin case. Make sure the thread is placed correctly around the bobbin case so that it doesn’t get tangled. After the bobbin is in place, you’ll need to lower the feed dog and raise the presser foot. The feed dog helps hold the fabric in place, and the presser foot ensures that the material doesn’t shift.
Once all of the pieces are in place, you’re ready to begin sewing. Turn the hand wheel on the side of the machine and make sure that the needle is traveling through the fabric and thread smoothly. To ensure that the thread is properly tensioned, you can check the stitch length and adjust the tension wheel as needed. Additionally, it’s important to check for any knots in the thread or tangles in the thread before beginning to sew.

Setting the Stitch Length

Now that your white rotary machine is threaded and ready to use, you’ll need to set the stitch length. The stitch length determines how frequent stitching will be, thus affecting the look of the finished project. Generally, the longer the stitch, the quicker the sewing time and the looser the stitches will be. For most fabrics, you’ll want to keep the stitch length between 2.5 to 3.5 millimeters.
Before you set the stitch length, make sure you check the fabric you will be sewing. Different types of fabric require different stitch lengths. For example, if you’re sewing a lightweight fabric like chiffon, you’ll want to use a shorter stitch length. On the other hand, for heavier fabrics such as denim, you’ll want to use a longer stitch length.
Once you’ve determined the type of fabric you’ll be sewing, you can set the stitch length. The stitch length is usually set by turning the knob on the side of the machine. Most white rotary machines will have a dial or knob where you can select the desired stitch length. Make sure you turn the knob until the number on the dial is set to the desired stitch length.

Types of Stitches

Once you have the machine threaded and the stitch length set, you can begin to explore different types of stitches. White rotary machines come with a variety of stitches, including straight, zigzag, and decorative stitches. Each type of stitch is ideal for different sewing projects, so it’s important to choose the best stitch for your project.
For basic stitching, most people will opt for the straight stitch. This is the most common stitch used for most sewing projects, as it produces clean, uniform stitches. The zigzag stitch, on the other hand, is ideal for tougher fabrics, as it allows the stitch to spread over a wider area, providing more give in the fabric.
The decorative stitch is perfect for adding a special touch to any project. These stitches are usually intricate and detailed, and can be used to create beautiful, decorative patterns. Additionally, some machines come with built-in embroidery stitches for adding special embellishments to your projects.


Once you have your machine threaded and the desired stitch set, you may encounter a few problems such as tension and timing issues. The most common problem with white rotary machines is tension. If the fabric is too loose, the stitches won’t be neat and tidy. To fix this, simply adjust the tension wheel until you get the desired effect.
If you’re experiencing issues with timing, the first thing to check is the drive belt. Make sure it is not frayed or worn out, as this can affect the timing of the machine. Additionally, a worn out belt can cause vibrations, which can damage the machine.
The last issue you may encounter is bobbin release problems. This is usually caused by improper threading and knotting of the thread. To fix this, start by removing the bobbin case and rethread it, paying extra attention to any knots. Once the bobbin is rethreaded and free of knots, you can replace the bobbin case and you should be good to go.

Safety Tips

It’s important to always keep safety in mind when sewing. While white rotary machines are fairly safe to use, it’s still important to use caution and pay attention to the machine while in use. Here are a few important safety tips to keep in mind:
Always make sure you are using the right size and type of needle. The wrong needle can cause damage to the fabric or the machine. Additionally, always check the needle for any damage before each use.
Never force the fabric through the machine, as this could damage the needle or result in a less than desirable stitch. Additionally, never leave the machine unattended while it is in use.
Finally, always make sure to unplug the machine when not in use. This will help prevent any accidents or fires.


To get the most out of your white rotary sewing machine, it’s important to take care of it. Regular maintenance will help ensure that your machine runs smoothly and lasts for many years.
There are a few simple steps you can take to maintain your machine. Begin by cleaning the machine after every use. You can use a soft, damp cloth to remove any dirt or dust that has accumulated on the machine. Additionally, make sure to regularly oil the machine. If you’re not sure where to oil the machine, refer to the owner’s manual for instructions.
It’s also important to be diligent about replacing the needle. Needles dull over time, which can result in uneven stitches or damage to the machine. Therefore, it’s important to replace the needle with a new one after a couple of stitches.
Finally, it’s important to check the belts and other components on the machine regularly. Look for any signs of damage or wear and tear, as these can affect the performance of the machine. Additionally, check the electrical cords for any frays or damages. If any of these components look worn out or damaged, have them replaced by a professional.


Threading a white rotary sewing machine may seem intimidating, but once you understand the basics, it’s a fairly straightforward process. Once the machine is threaded and the stitch length is set, you can explore different types of stitches, such as straight, zig zag, and decorative stitches. Any issues you might encounter, such as tension and timing problems, can usually be solved with a few small adjustments. It’s also important to keep safety in mind when sewing, as well as follow a few routine maintenance steps to ensure your machine stays in good condition. With a little bit of practice, you’ll be threading and sewing with your white rotary sewing machine like a pro.
