Query: Classic, but Difficult

Ian Bain was perhaps the first to attempt to create a "how-to" book for the "average" artist to learn Celtic design. This is a classic treatise, and no Celtic artist's library should be without a copy. That being said, his explanations are not always as clear as he thinks they are, and if this is your only source of instruction, you might walk away feeling frustrated. For the beginner, I find the books by Aidan Meehan to be easier to follow and more likely to produce early successes. I am NOT not recommending this book; there are areas that Bain investigates that cannot be found in Meehan's books, but for a starting place, I recommend the latter's books instead.
