Learn How to Thread a Singer Sewing Machine Bobbin with These Lessons

Before you can sew your first stitch, you must first set up your sewing machine. Sewing machines might be intimidating to learn how to use, but with practice and a few sewing jobs under your belt, it will become second nature.

For bobbin threading, what are the steps? The bobbin of a Singer sewing machine may be threaded in three major ways:

  • Upper thread system threading
  • Using the bobbin thread as a needle
  • Pulling the bobbin thread up

Front-loading and top-loading systems are available. Depending on your system, the procedure for threading a bobbin may be different. We’ll cover through each of them in detail in today’s article!

Front-Loading System and Top-Loading System for Inserting a Singer Sewing Machine Bobbin

You need to know the difference between front- and top-loading bobbins before you can use them. You’ll learn more about your sewing machine and how to detect bobbin issues if you do this.

Top-loading (or drop-in) bobbins and front-loading bobbins are the two kinds of bobbin mechanics. The top-loading approach is preferred by certain users. Personal experience, on the other hand, will be the only determining factor.

In either situation, the bobbin is inserted into a bobbin box within the sewing machine. When using a top-loading machine, the bobbin case is kept within the machine. However, on front-loading machines, you must remove it before inserting or removing the bobbin.

In both methods of sewing, the shuttle is used to draw the top thread around the bobbin. Using this procedure, the sewing thread from the bobbin is taken through the needle plate and twisted up in the cloth by the needle. This procedure culminates in the stitch.

The shuttle on a top-loading sewing machine has a rotary hook, which means it rotates in the same direction all the time. The bobbin is horizontal in this method.

Most (but not all) front-loading sewing machines include an oscillating shuttle hook. In order to move the top thread around the bobbin case, it makes the shuttle to go back and forth. As you can see, it is positioned vertically in this situation.

Neither of these two systems is better or worse than the other naturally. In certain cases, people contend that one variety is better than the other. Nevertheless, I feel it is more a function of the sewing machine’s general quality and the experience of the operator that determines this.

There are two types of drop-in bobbin bobbins: top-loading and bottom loading. It is possible to tell how much bobbin thread is left and prevent running out in the midst of a critical sewing section if the bobbin cover is transparent.

Front-loading bobbins have the benefit of being simple to adjust. Despite the fact that all sewing machines have a thread tension control on the top, many sewists are unaware that they may modify the bobbin tension. Front-loading bobbins make this process considerably simpler because to the little screw that allows you to fine-tune the tension.

Even if you’re confident in your abilities, never touch it if you aren’t sure what you’re doing. The top thread tension is easier to adjust. It’s also difficult to return to the previous state after making a modification.

How to Thread a Front-Loading Bobbin System: Steps to Follow

  • Decide on the best method of accessing the loading area, which is an accessory container that must be removed. It unlocks the free arm machine and displays a little hinged cover that opens to reveal the bobbin below it.
  • To get access to the bobbin case, remove the lid from the case.
  • Raise the metal clasp in the center of the bobbin case so that you can grip it and remove the bobbin case out of the bobbin case.
  • If you invert the bobbin case, the bobbins will come tumbling out. Eliminate it from the case in order to completely remove the thread’s tail.
  • Rotate the freshly wound bobbin so that the thread comes off in a clockwise direction to the left.
  • Carefully insert the bobbin into the bobbin casing. Check to see that the thread is still moving in the clockwise direction.
  • Gently pull the thread through the slot at the edge of the bobbin casing.
  • Gently pull the thread beneath the flat “finger” until it slides out into the side aperture of the case. Two small “teeth” protrude from the end of the finger and extend around the edge and into the aperture. Make certain that the thread goes through the teeth. It is possible to hear a faint “click” when this occurs.
  • Hold the bobbin casing in your hand so that the hinged latch is facing you. Using your finger, you can prevent the bobbin from falling out of the machine.
  • Using that long “finger,” insert the bobbin casing into the shuttle aperture using the long “finger.”
  • Tighten the bobbin case by pushing it into position and twisting it slightly if necessary until it snaps into place.
  • Thread the top of the sewing machine with the bobbin thread that has been pulled up.
  • Move the handwheel with your left hand to lower the needle while holding the top thread to the left. The shuttle will start to travel around the bobbin case at this point.
  • As you raise the needle, you’ll observe that the top thread is pushed from right to left over the bobbin case. This is normal.
  • Pull the top thread up through the presser foot’s hole until it is taut. This process raises the bobbin thread out from beneath the needle plate and into the needle plate. While keeping the top thread against the needle with your right index finger, pull the bottom thread taut.
  • Both threads should be pulled under the presser foot, through the hole, and then returned to the left side of the machine.
  • If you have to take the accessory compartment out of the machine, shut the cover over the bobbin loading area and reassemble it.

How to Thread a Top-Loading System: Steps to Follow

  • To release the bobbin cover, push the button or lever on the side of the cover. It has to be moved to the right side of the screen.
  • Take the bobbin cover off of the machine and discard it. You can now see the bobbin that is incorporated inside the machine.
  • Hold the bobbin so that the thread comes out to your right and towards you.
  • Insert the bobbin into the designated location (the bobbin case). With your left index finger, secure the bobbin in place. The thread should be pulled to the left using your right hand. The metal bobbin casing will most likely have two slots on the side, as seen in the illustration. You must make the thread depart the first and re-enter the second in order to complete the task.
  • Use your left hand to draw the thread all the way to the rear of the sewing machine.
  • Holding both the bobbin cover and the bobbin thread in place with your right hand, replace the bobbin cover. The thread should come out of the space between the bobbin cover and the needle plate when the bobbin is removed.
  • If you haven’t already, start by threading the sewing machine bobbin.
  • Keep the top thread in your left hand while gently lowering the needle by rotating the handwheel with your right hand. Then, with the help of the handwheel, raise the needle once again.
  • At this point, the bobbin thread, which you can see looped around the top thread beneath the needle, will have been forced up by the top thread. With your right index finger, carefully bring the top thread up through the aperture at the front of the presser foot, and then release the thread. This should be done while holding it against the needle. The bobbin thread must be pulled up through the needle plate hole in order to be effective.
  • Using your left hand, pull both threads back under the presser foot, through the aperture, and towards the rear left.

That could have seemed complex at first, but it isn’t at all. Once you’ve figured out how to accomplish this on your computer, it shouldn’t take you more than two minutes to complete.

Troubleshooting Bobbin Thread Issues

On the underside of your sewing machine, one of the most common problems is a mess of twisted bobbin thread. Any project you’re working on might be quickly derailed by any one of these things. However, don’t be alarmed––this problem is usually easy to fix.

It’s common for consumers to believe that their sewing machine has a bobbin issue, but that’s not always the case. To fix it, you don’t even need to contact a repairman! An equal and smooth winding of your thread isn’t your fault; it’s the bobbin’s fault.

The looping bobbin thread is often caused by the sewing machine’s top threading. This is how you can figure out what’s wrong:

Take Care to Thread the Machine the Right Way

Rethread the top component of the sewing machine and ensure that the thread goes through all of the thread guides before reaching the needle. Rethreading the owner’s handbook that came with your sewing machine is your finest resource when it comes to threading it.

At all times, keep the presser foot up while threading the machine. The thread will sit properly if the presser foot is raised.

The thread will not sit correctly if you push the presser foot all the way down. There will be no tension applied to the thread if the tension disks aren’t properly positioned in the thread. Because of this, the stitch fails.

Change The Needle

Recurring problems with looping bobbin thread may be solved by switching out the sewing machine needle. Keep an eye on the needles you’re using, as well as their compatibility with the cloth you’re working with and the task at hand.

Has the needle been twisted by any chance? When it comes to the top threading, the needle is a vulnerable component. Never forget to provide tasks to the food dogs.

If you pull the material to the rear of the sewing machine, you risk bending the needle. Stitching problems might arise as a result of this.

Make Sure The Bobbin Is Up To Date

It is possible that the bobbin is at blame if you have not threaded it properly. If this is the case, it might be the root of the issue.

If the threading is not smooth, uneven, knotted, or excessively loose on the bobbin, you know something is wrong. By understanding how to wind a bobbin, you can eliminate this risk.

Additionally, make sure that the bobbin is properly inserted into the casing. It’s essential to consult your sewing machine’s instruction manual to learn how to put the bobbin casing in place. In the event that you don’t have a copy of your sewing machine’s handbook, you may get a copy online for free.

The bobbin goes in a detachable bobbin casing. Threading properly and forming an upside-down “V” is the goal here. If your machine uses a case rather of the modern drop-in bobbins, this will occur. Under the metal and out of the bobbin case’s side, the thread is then threaded.

Cleaning the Machine

Please tell me if it still doesn’t work. When was the last time you had it cleaned? Is the bobbin case clogged with lint and thread wads? Is your top thread shredding and maybe leaving fragments in the threading route, as you may have noticed?

Time to get the lint out of the way! You may clean and oil your sewing machine, as well as conduct any other regular maintenance duties that are outlined in your sewing machine’s handbook.

Frequently Asked Questions (FAQ’s)

How many yards of thread are stored on a bobbin?

Bobbins of the Style M variety can carry approximately twice as much thread as those of the Style L variety (210 yards compared to 110, depending on thread type and manufacturer.) This allows for a much greater amount of quilting to be completed before the bobbin has to be replaced.

What is the purpose of threading a bobbin?

When you use a sewing machine, the top thread and a bobbin thread entwine to make a strong stitch that links two layers of cloth. This is called a “stitch.” You will need to start by learning how to thread the machine, which is the first thing you will need to learn. Winding and inserting the bobbin is the portion that may slow down a lot of beginning sewers.

What is the most suitable thread for bobbins?

Cotton and polyester are both excellent options for bobbin thread; selecting one over the other comes down to individual taste. It would seem that certain sewing machines like polyester fabric since it is somewhat stronger. If the 50-weight cotton thread you’re using keeps breaking, look for a different brand or try polyester thread instead.


Even experienced sewers may feel intimidated by sewing machines from time to time. When you learn how to utilize them, you’ll save yourself a lot of time and effort in the future. A bobbin may be threaded in no time at all if the instructions are followed carefully.
