I live where there's no ability to attend a class. This book is so terrific about explaining things. I bought it first and studied it (it's very easy to understand and there are great examples of cards) and by the time I bought my pens, I tried blending some flowers, and had success the first time! Totally recommend!
For the beginner this may be a very informative teaching guide. I've had my markers for a while and have watched endless tutorials on YouTube. I guess what you can learn from YouTube videos is enough. You really just need to play with them and learn as you go. The book does have some cute projects in the back.
