I agree with all ..it depends on what u are comfortable doing..the main rule as I see it with home machine quilting..is start from the center and work out..I have turn my quilts..not turn them..gone top to bottom ..bottom to top..side to side..I do feel top to bottom is best ..if there is any give in the bottom layer.it doesn't bunch going from top to bottom usually..where as the side to side can sometimes stretch the material..but again as always ..it is a personal opinion
