Overview
It has been a while, but here is another report on changing to a new croquis sketchbook.
The previous one is here:
Changing from the 16th to the 17th
The one on the left is the 16th, and the one on the right is the 17th.

And this is a chart showing the periods when I used each croquis sketchbook.

The periods for the 15th and 16th were short! Well, of course, that was when I was studying for the Eiken Grade 1 test. For the Grade 1 essay, I needed two full croquis sketchbooks’ worth of study.
I will keep it light and end here for this time.
