The only "con" I know, is be careful where you buy your batiks.
Hoffman and Hoffman make very good batiks and have fair labor laws and do not promote child labor or endangerment. Believe it or not, if you buy cheap batiks you are supporting children and /or women that sometimes are even caged for their labor. Our department of labor is working on this, in the 15 or so countries that make batiks. But as they told me, in response to a letter I wrote to the Secretary of Labor...the power only lies in the people who buy the product in the end. As for me, I only buy from the companies that I know. Just a thought.
