One other lesson that I've learned is that it's easier to FMQ on the practice squares because you can move them around so easily. When it comes to your large quilt, think of it divided into 4 quadrants. Then start in the middle and work to the outside and bottom of each quadrant. You have to stop and move your quilt frequently because it drags against the edge of your table and machine. As soon as it becomes hard to move around while stitching, stop and re-adjust the quilt. Good luck!
