This is a prompt about free play. About hanging upside down on the imaginary monkey bars and looking at the world from a different perspective. Create a journal page with the journal upside down. The idea is not to create a page in reverse but to actually work with your book upside down. The top is the bottom and the bottom is the top.
Envision how you would like the page to look when you turn it around, but RESIST the urge to "check" it and see how it looks. Good luck. May the art journaling force be with you.
Leave a little space on the page for your written journaling. Then turn the page around properly so it's no longer upside down and WRITE about the experience. Was it disorienting? Refreshing? What did you learn? What surprised you when you turned the page around?
