Another circle concertina book

I wanted to try out this book structure for a wedding anniversary greeting.   I made a smaller foam print so my computer-printed message would not be obscured.  The quadrant box was covered with scrunched tissue before being painted.

It's an easy book to make but care is needed to align the sections when sticking them together.  Using the eight pages, I find there is no need for anything to hold the book in its open circular position, but that might not be the case with fewer pages.
