Artist's Journal Workshop is a wonderful book for anyone looking to start a sketch journal. It's a 144-page paperback with beautifully laid out pages.
It's packed with lots of tips on finding ideas, and from there, you can discover which style suits you. This book really brings across how fun sketching can be.
There are 27 artists who share their sketch pages in this book. Some of them are Danny Gregory, Nina Johansson, Liz Steel, Lapin, Cathy Johnson herself, of course, and many more. They also share their insights.
Since this book is about journaling, the examples are mostly about illustrating what you see. It can be drawing people, places, animals or food. It's very inspiring to check out all the artists' work, even the seemingly mundane stuff look interesting when illustrated.
Highly recommended, especially to sketchbook lovers.
