I recently recorded a flip-through of one of the books I'm working on because I'm in the process of moving from a one-sided book that used the Original Grey pages to a double-sided book that uses Low-Ink. Initially, it was a lot of work to move the information from the old pages to the new pages but I've found that the double-sided layouts give me so much more creative freedom (and save me so much paper!) so it's definitely been worth it. Enjoy!
