Tried a new needle? Or it could be that you've developed a burr on the hook. I'm assuming everything else is the same as it was before.

I've found that if you put the needle in at even the very slightest angle the thread will fray. Make sure the slotted side of the needle is facing the way it should be.  Sometimes when I put a new needle in, I have it just right, but then while turning the screw it somehow gets turned a tiny bit. This will cause the thread to fray.

You may also be using too small of a needle eye for the thread.  If you're using a size 92 thread, I would suggest a size 22 needle.  The thread could also be running a little fat.

materials being sewn can be a factor.  Check every piece of metal that your upper thread passes over on the machine to look for grooves in the metal.  These are just more contributors that can potentially cause your thread problem.

Sometimes thread tension is the problem.

I may have heard this on this forum. If so, credits to the original poster.

A thread went into a bar. The bartender said, "Get out of here. We don't serve threads."

The thread went outside, tided itself into a tight loop and combed and tassled its' ends. The thread then went back into the bar.

The bartender said, "Hey, aren't you that thread I just threw out of here."

The thread said, "No. I'm a frayed knot!"

LOL I love this joke! A frayed knot! (Afraid not!) Get it? ;D

Below you will find several guides that were posted a year or more ago in a thread that I started, I've grouped them all together for your convenience.  I thank all the original posters as these have helped me and many others I would expect.
