Last time, Mr. Ninomiya provided me with the Yosegi for the pages, but this time I made the Yosegi myself.
It's a simple pattern, but I had a hard time getting it just the way I wanted it, and I realized once again how skilled Mr. Ninomiya is.
I also changed the way I made the eight corner parts that represent the front and back covers, using a technique called spline joint.
This technique is used for both decoration and strength improvement.
The trick is the same as last time.
