As I was reading through this - my very thought was QAYG. Being that all the shirts are basically(hopefully) the same size really makes this so much easier. Measure the backs and fronts of the patterns, and that will give you the size block you will need to make. You could put the fronts all on one side with the matching backs on the other. QAYG each strip block by block and even do your quilting in each block to make it easier later.
