Understanding Your Creative Partner! Bobbins! May 3, 2023

Hello Stitching Community!

In this Email:

Bobbin Knowledge is essential to achieving a perfectly balanced stitch!

  • Be Bobbin Savvy!
    • Is there a universal bobbin that fits all sewing machines? NO!
    • Can you use metal bobbins if your sewing machine has a bobbin "low" indicator? NO!
    • Does the direction that your thread pulls off your bobbin matter? YES!
    • Does your bobbin have to be tightly wound? YES!
    • Does your weight (size) of the bobbin thread have to match your top thread? NO... BUT!
    • Is there tension on your bobbin thread? Is it adjustable? YES & YES!

Once again it is time to explore your Creative Partner, Your Sewing Machine!

  • Why am I addressing this topic?
  • I see loads of machines that are brought in to me for repair and what do I see? 
  • Many of the machines have multiple sizes and shapes of bobbins that will not work with their machine! 
  • The good news is that once the correct bobbin is used, the machine is fixed!!!!!
  • Don't be embarrassed but do become sew knowledgeable!


Size Does Matter!!!

  • Perhaps it is difficult to see all of the various shapes and sizes of the bobbins in the picture above. Zoom in and take a look!
  • Trust me the bobbins are very different!
  • There is not a universal bobbin even though you may have seen ads for them! 
  • **Always select the bobbin that is designed for your machine's brand and model. For example: Pfaff sewing machines have a number of different shapes and sizes of bobbins! Ask an expert!


Metal or plastic?

  • You will also notice that some of the bobbins are metal and some are plastic.
  • If your sewing machine has a bobbin sensor, a light must be able to pass through the bobbin to reach the sensor, so it's plastic for you. 

How should your thread spool off?

  • If you have a bobbin case that is like the picture on the left, your bobbin needs to turn clockwise.
    • ​​​​​​​A dot placed on the top of the bobbin will turn to the right.
  • If you have a bobbin case that is like the picture on the right then your bobbin needs to turn counterclockwise.
    • ​​​​​​​A dot placed on the top of the bobbin will turn to the left.


Does your bobbin need to be tightly wound?

  • Yikes, look at these! 
  • Your bobbins must be wound tightly. 
  • Not loopy, not spongy!
  • The loose threads below will get caught in the bobbin case as they try to spin.
  • Most times bobbins like this can be re-wound on another bobbin so the thread does not go to waste.
  • Having issues winding a bobbin? Ask us for help!


Does the thread used in the bobbin have to be the same weight (size) as your top thread?

  • Your machine is adjusted to have a balanced stitch with a 50/3 thread.
  • A heavier or lighter thread can be used in the bobbin if the tension on the bobbin thread is adjusted.
  • The thread on the right is the correct weight!


How to make adjustments on the bobbin case?

  • There is a small screw on your bobbin case that can be adjusted.
  • Pictured on the Left. Adjust the bottom screw
  • Pictured on the Right. Adjust the screw shown at the tip of the awl.
  • Be Careful! You can adjust the screw too much and the tensioning pieces will fly apart!
