I have been working on my 'A good idea at the time" bags and have been asked how I get pattern on the fabric to match so well.
I don't do any thing fancy like pattern matching, I just put my selvedge edges together and cut through both pieces. I am only using the fabric the way it was printed and it is usually printed edge to edge.
But beware of the fabric where the print runs in the other direction, it just will not work. You are going to have to pattern match this one.
