Thanks for writing.
I just took a class last month and the teacher said this happened to him. His blocks were good then all of a sudden they were off. It was the bobbin thread. I always make sure to use the same top and bottom; your machine will also thank you for doing this, no tension problems. I have a 1/4in foot but I move my needle over to a certain # when I'm piecing to make sure I have the scant 1/4 in. I need the foot because it has the bar that keeps my fabric straight so I use it and then just adjust my needle to the same spot each time.
