Bobbins...

 Have you ever wondered about your bobbin and the method of insertion?  How about how the bobbin insertion affects the quality of stitching?  Many machines either have you insert the bobbin with the thread either like a "p" or a "q".  Seems fairly simple, right?

For 20 or so years, I have sewn on a Husqvarna electronic or computerized machine.  They have specialty bobbins that can only be inserted one way.  So, the issue I am about to show is not something that I have seen or thought about in a long.  The machine that I currently use the most is a Bernette B77.  It is a fairly nice machine with it's own special quirks but when I purchased it a couple of years ago I wanted a machine that made beautiful buttonholes.  It does make the beautiful buttonholes one after another unless there is a user error.

Back to bobbin, I am setting up to work on another garment and decided the machine needed to be cleaned.  It must have been a while as it really needed cleaning in the bobbin area badly.  Cleaned the machine and put everything back together.  Proceeded to wind the bobbin and thread the machine.  This is when the "brain fart' happened.  I blanked on which way to put the bobbin in.  I put it in using the "q" method.   If you did not guess, I put it in wrong.  The machine will stitch with the bobbin not inserted correctly.  Here are the results of the bobbin threaded incorrectly and the bobbin threaded correctly:


In this picture the stitching on the right in with the bobbin inserted incorrectly.


In this picture, the top stitching is with the bobbin inserted incorrectly.  

Can you see the difference in the stitching?  You can really tell by feeling the two lines of stitching.  It feels like the tension is wrong and looks like the top thread is riding on the top of the fabric.  Amazingly, the machine did not object other than what you see in the picture.  No funny noises.

So, would you have guessed that the issue was the bobbin thread? or would you have thought the issues with mis-threading the upper thread?

We are never to old to learn, are we?   I have been stitching fifty years or so.  

Happy Stitching!
