Hey Toby, yeah I don't think I explained it well, sorry! I was able to duplicate the planet sheets into a four page PDF, each page being a planet sheet. Then I can print them as a booklet (four to a sheet), multiple copies of each page, and fold/staple them into a booklet. This works great for keeping the planet sheets together, but since they're a landscape sheet it means the booklet also needs to be turned to landscape to write in it. Not a deal-breaker by any means, just more of a convenience.
Thanks again!!!
