Recently, I gave an Origami Connect workshop on my origami book model Long Story Short. Preparing for the workshop motivated me to revisit an idea which I had several years ago, right after designing the model, namely to design a book whose cover would be decorated with a tessellation-like pattern. I was not happy about my original attempts since either the pleats radiating out of the pattern affected other parts of the model, or I had to severely limit the kind of pattern used.
Fortunately, this time around I was able to design a nice transition between the tessellated part and the area of paper used for folding the back cover and pages. The result is a tessellated cover, and a completely smooth back, as well as no visible creases on the pages of the book, all from a single sheet of paper. This technique is quite similar to Flagstone Paneling.
