We made each page on separate squares of backing fabric, and then I eventually put them together this week.
The book opens in an unusual way, as I show and try to explain below. Then I took close up photos of each page.
So first up is the front page
Flip the front page to the left to reveal the next 2 pages
Next, flip the right hand page down
Flip the bottom page to the right to finish opening the book
Finally the back page
Here are close ups of each page (except the front and back)
