I finally browsed around the internet to see what was happening. I discovered that what is happening is called "lashing", which happens when you go around curves too quickly. Solution according to the writer is to slow down on the curves.

Since I don't have a speed adjustment for my machine, I can't just mash the pedal all the way to keep a constant speed, and thusly, only have to concentrate on how fast I move the fabric. This is going to take a lot of practise.

If I can't do two things with my hands like when I have tried to play a musical instrument, I will be stuck with straight line quilting. I've never been able to coordinate my two hands to do two different things at the same time. Had this problem my whole life, other than I finally learned how to touch type, so maybe there is hope if I persist long enough.
