I hadn't heard of artist trading cards until I came across this book. After placing an order on Amazon, it was recommended. It teaches a variety of techniques that could be used in other art projects. My daughter and I have really enjoyed it. She can produce so many of them so fast. I have only made a few. I tend to use them when I am thinking of larger projects. I do artist trading cards first, then I can do two or three or more look and decide which version I like the most and make it into a larger piece of art.
