Even though I have used Illustrator for several years, I found the steps and tips a little confusing. I bought this book to increase my knowledge.It wasn't too helpful, especially when steps are skipped, and the tips don't correspond with the instructions. In one area the instructions read, "expand and ungroup, (about a million times) to delete the wireframe." Didn't work for me.
