With the growth of blogging, websites, and online direct-download and other forms of Internet merchandising, I notice a trend in many artistic/crafting "instruction booklets" in the English speaking world. They're short. They're superficial, and they're expensive for what little information they contain. It's no longer about sharing ideas and creativity, it's about making money above all. "Zentangle" is no exception. On the mother blog, we are told: Everything you need to create beautiful Zentangle art can fit in your pocket. This easy to learn method of relaxed focus can be done almost anywhere, alone or in groups, without any special abilities or costly equipment." (emphasis mine)
And then on that blog as well as this book and other online resources, they tell you that you really must buy their special Italian-made pressed-paper "tiles" (3 inch squares), the special Japanese-made Sakura Micron pens, and, oh yeah--you really should take a special course from a CZT (Certified Zentangle Instructor). Or you can get the full kit with DVD for about fifty bucks (and that's if you live in the US; I shudder to think what the international postage for that baby costs). You won't find much in the way of real how-to information in the books, because yeah, this is an industry now, baby. The whole thing is directed to getting you to splash out on the package deals to learn their "philosophy" and "techniques." Now, wait a minute...what happened to "without any special abilities or costly equipment"? I guess cost is relative. But then 50 dollars is about half my weekly housekeeping expenses budget.
Explanations of techniques in this book as in the rest are very superficial, skimmed over, because, yeah, you're gonna take that course, aren't you? Aren't you?
But don't let them take away your fun. Take it easy, take it slow, and don't believe everything you read online or in this book. Draw a few 3 inch squares on some printer paper (or a paper bag, or what have you) and give it a go. There are some excellent videos on YouTube by normal folks--along with a few by "CZTs" that are aimed at getting you to invest in the books, the course, and the expensive "kits".
