Sketching can be even more fun if using a themed sketchbook. These can be made or decorated in any way you wish. You are only limited by your imagination.
My recent article in Artist's Back to Basics' has just been published with hints, tips and information on how to make your own sketchbook.
There are also many excellent articles in this edition #6_1. I usually do an article for every issue and have been doing this since the magazine's inception. It is sometimes a challenge to come up with something new and different and it is great to expand the imagination with various techniques, subjects and ideas to share.
