   Well, that's not good.  The only suggestion I can think to make -- if your machine's thread tension is otherwise okay -- is to try a larger needle.  Using regular all-purpose thread?  Does your machine's tension self-adjust, or do you need to manually adjust it?  Whenever I've had this problem I've had to go on a hunting expedition and find a little tiny piece of thread caught somewhere in the bobbin assembly.  Sometimes it's required a flashlight and a magnifying glass.  I wouldn't trust it through the wash either.  What fabric are you using?

   I'm sewing with a good old Bernina self-adjusting tension. I use a stitchlength of 3 on my Bernina. Sewing on a Polyester Cotton. I think what happens is that when I turn the corner the stitches don't form properly because of the longer stitchlength. Does this make sense? I also stitch from the top - bottom. Maybe I should try from the bottom - top? Yes, Im using Guttermann all-purpose sewing thread.

   Yes, I'm on a Bernina too, with self-adjusting tension.  Hmm.  Everything sounds right.  I'm sure you've tried replacing the needle.  Have you tried Needle Lube on the needle?  That's my last suggestion....D.

   I've had this problem too and it can be so frustrating.  I think what is happening is the needle is not catching the bobbin thread for that stitch and you just have to figure out why.  Changing to a new needle has helped.  Rethreading has helped.    Have you checked the bobbin case for lots of fluffy debris?  Actually, it doesn't have to be that much!  Just changing from one thickness to another probably boggled the machine's brain and it balked, and it could be because of any of the above. 

   Did you pre-wash the fabric and use a softener sheet in the dryer?  That's a big No No.

   Good luck, will be looking for how you solved this problem.
