It's not really a journal at all.
But you could probably figure that out on your own.
Artists' journals aren't quite what you'd think of as a diary. There might be words. There might just be a color. There might be a testing of a new technique or a drawing of something outside. There might be photography, there might be a story, there might be pasted in bits of things found on the ground.
There's no rhyme or reason, except to the one that creates it.
You're invited to look and stay a while. Relax. Have a drink.
Stay a while.
