I would get "Machine Quilting in Sections", by Marti Michell. It contains several QAYG methods:

I don't see anything wrong with the method used. You could modify it by squaring up your blocks before quilting, then cut your batting 1/4" smaller on all 4 sides (half inch off the length & width). Then when you join the blocks, you don't have the added bulk of the batting.
