There are probably 12 different methods. Some people don't like any of them because of how they prefer to work, so don't beat yourself up over it. My favorite is to quilt in sections and then assemble. Using Sharon Pederson's method is also very nice. One that I haven't tried yet - you still have a whole front and back. You cut the batting into 3rds. You only have the batting in the center. Quilt that. Then attach the batting for one side to the center. Quilt that. Then do the same for the other side. This method reduces the bulk so that you can get the center done. You also don't have to do a bunch of assembly at the end. You are just attaching the batting to batting.
