How To Fill A Bobbin On A Singer Sewing Machine Correctly

According to Singer, you must wind the bobbin before threading the sewing machine. Follow these easy steps to get started:


Step 1. Set the machine up

  • Place the thread spool on the spool pin
  • Install the spool pin cap over the spool’s rim to keep the thread from entangling and forming knots
  • Push the bobbin winder pin as much as you can to the left
  • Thread the guide accordingly until you can get the thread end through the hole on the bobbin’s rim 

Step 2. Wind the bobbin

  • Put your bobbin to its pin and push the winder to the right to keep the needle from moving
  • Hold the thread end gently as you step on the machine and start winding the bobbin
  • Like all sewing machines, Singer will stop automatically after the bobbin is full
  • Cut the thread and remove the bobbin from the winder pin by pushing it to the left
  • Trim the thread ends at the top of the bobbin to finish

Is A Drop-In Bobbin Better?

Sewing machines that use a drop-in bobbin are more popular because this bobbin type is more beginner-friendly. This is because they use a transparent cover to know how much bobbin thread is left, and threading a drop-in bobbin is way easier since you don’t need to remove the accessory compartment as with front-load bobbins. You may also notice that you experiment less with a drop-in bobbin with regards to tension. 


Is a front-load bobbin better?

A drop-in bobbin is convenient for beginners, but the traditional front-loading bobbin also offers some advantages. For example, you can easily adjust the bobbin tension via the screw on the bobbin case. You can also replace the bobbin case itself if you notice issues with tension. 


Are Metal Or Plastic Bobbins Better?

Identifying which to get between metal and plastic bobbins depend on the case you have on the sewing machine. For example, a metal bobbin case needs a metal bobbin, while plastic cases must use plastic bobbins. Using an incompatible bobbin can damage the case and also affect your sewing experience. 


How Do I Know What Size Bobbin To Buy?

Bobbins come in different sizes, and you should be able to determine what size to buy based on your bobbin case. It should fit inside the case without sliding around, but it shouldn’t be too big that you can’t place it inside the case. You can also refer to your sewing machine manual because the brand will mention the size of the bobbin to purchase. 

Speaking of placing the bobbin in its case, read how to put a bobbin in a sewing machine to know the correct method. 


Can You Hand Wind A Bobbin?

You can hand-wind the bobbin if you don’t have a bobbin winder, but it will depend on the type of thread. Hand-winding the bobbin will be easy if you’re using thick materials, but fine threads can take too much effort to ensure that they won’t get tangled.
