So, basically a Tumbler quilt make into a rectangle?
Oops, not a rectangle, you actually deal with the Tumblers .

How big exactly do you want the quilt to be?
Everyone's queen-size is different.
How wide and tall is your Tumbler block?
A little division and you've got your answer as to how many "waves" you need across the quilt, and how many blocks long the wave needs to be. (Although you have to take into account the width across are made up of the widest and narrowest portions of the Tumbler.)
