For this page, I created a waiting game spinner. It was incredibly simple using Photoshop, card stock, cardboard, and some spinner arrows I found here, but you could just google "4-inch arrow spinners" and see what you come up with; I like to shop around for the best deal.
I made this the last page of the flip book, so it could adhere to the sturdy cardboard cover. Once I had created my spinner in Photoshop, I sized it to my flip book (5x7) and printed as many copies as I needed (8). May I humbly recommend that you make at least one extra? These tend to have a way of falling out monorail window vents, over balconies, and the like. (Not that those things happened to us.)
Ta-da! You now have a boredom buster at your fingertips - just don't forget it in the room! And if you'd like to use my spinner page, you can download it here for free.
Until next time, may all your days be filled with fairy dust!
