The courses are absolutely amazing, and I plan to sign up for all of them! The content is very comprehensive and easy to understand. Jyotsna has a PhD in chemistry and not many other people in the world would have her intimate knowledge of the dye and ink-making processes. Her passion for sustainable art making and organic farming is second to none. The price of the courses are also very affordable, and I would highly recommend this course to anyone who is interested in sustainable art practice.
