I have dozens of unfinished sketchbooks and art journals. Literally dozens. The reasons a sketchbook or journal isn't finished are as varied as the mediums used inside.
Some are themed journals, such as my "Field Guide to Southern Flora & Fauna" or "100 Faces" or "Field Guide to Southern Faces & Figures" and those obviously can't be worked on until proper subject matter is at hand.
Some are started and then misplaces, necessitating a new journal to be bought and begun. A few are going well until a sketch or project goes awry and I hate it with all my might and have to set it aside for awhile until distance allows me to see it anew and remember all of its possibilities again.
So when I finish a sketchbook or art journal, it becomes a prized possession. It receives a place on the shelf reserved for antique books and first prints. I'm exaggerating a little, but not much.
I'd like to take you on a tour of a few of the finished ones. This first one is the most basic. I made it years ago as an example of the sketchbooks my students would be making in my art class. What I found was that grown-ups loved it and wanted to make one of their own.
Part of the reason is because the book is so short. Finishing it is quite a bit easier and less intimidating than an 80-page journal. See for yourself:
