Booklet Sequence Ordering for Double-Sided Printing

This is completely for my sake and sanity, one of the random things I find myself doing and stressed over that could have been easier, and I don't want to forget when it comes up again.

In the last few weeks I've made two programs for two different plays in our area put on by homeschoolers and directed by amazing mothers of some of these kids purely volunteering their time.  The first one I had kids in the play and it was my way to help make it happen.  The second one was a favor for a friend (and we get free tickets because of it - bonus!).

I know there is a way to print it and have it come out right, but the place the first one was done just printed it double-sided so things were out of order.  It wasn't horrible, but I knew it was wrong.

I couldn't send off the second to be done the same way in good conscience, so I sat with the single-sided pages in the right spots on my lap, flipping back and forth.  Of course when I had fiddled and messed enough, I finally figured out there is an easy pattern to it all, as seen in this graphic.  Follow the black arrows down and the blue arrows back up, and voila, in the right order.

Like I said, for me next time.  I have a feeling I will get to do this again.

Sorry this is so random...
