Have you triple checked to see if your bobbin is seated properly? Is your needle seated properly? Those are the first things I recheck when ever I have any issues. Then if those don't work rethread top thread.

Whenever something like that happens, firstly, remove the thread and start over with re-threading it. It works for me. Also, Joyce Becker says on her DVD, that you should always have the presser foot up and not down, when threading, because it keeps all the thread going into the right grooves. Maybe it is worth a try for you. Be sure to hold those tails at the beginning, behind the needle, until you have gone a ways, and then cut them off.

Well, I've tried all the most logical things. Rethreading, changing needles, check the bobin, etc.

Now, I'm going to try walking away. Some days that works for me.

When I get back to it, if it doesn't work, I may have to change thread. I'm using some junk that was a throw in of 30 spools when I bought the machine. I don't even really know what it is. The writing is all in some type of "ese".

You stitched through your thread and it pulled up then the next stitch made it wonky. This only happens to me when I am going back and forth where I don't pay attention and stay next to the previous stitches instead of on top.

It looks like you have stitched thru your previous stitch. Sometimes happens when I move the fabric too slowly. I think that with practice this will go away, as you coordinate moving the fabric with the speed of the machine.
