« The Natural Dye Course offered by Apple Oak has been a wonderful experience. It's a well blended curriculum of the history and science of natural dyeing. Jennifer does an excellent job or leading and supporting her students through the course work. She provides support through problem solving, expanding on specific topics as needed and presenting clear and concise information. It is also a very accessible platform that has made it easy for myself who has a learning disorder (reading is hard) to navigate and use. Overall I would highly recommend the professional dye course to anyone seeking to further their knowledge of natural dyes and the fiber arts through dyeing. - Valeria Q. (Ireland)
« I have found this course really worthwhile, Jennifer is super knowledgeable, helpful and patient. At the beginning I was a little overwhelmed by the portfolio work involved but once I got stuck into it, I’m absolutely loving it! Seeing colour appear before my eyes from only tannin and iron has been so amazing and I can’t wait to move on to the other colors!!- Caroline B. (Switzerland)
« I am a complete novice when it comes to natural dying. The course sounded very comprehensive and supportive so I decided to give it a whirl. I am now almost 5 months into it and am absolutely loving it so much. Although it took me a while to get my head into the space of measurements and science, Jennifer and Tristan were very supportive with questions asked and made sure everyone was on the page. It has opened up a whole new world to me and I would thoroughly recommend it. There has been a lot covered so far so my advice would be to tip away at the work so that it doesn't become overwhelming especially if your a beginner like myself. I'm looking forward to meeting the class in person and seeing the studio in the flesh. - Louise G. (Ireland)
« Jennifer and Tristen have put together an amazing course! I have been naturally dying for for a number of years and thought a knew a lot, until I began my journey with The Natural Dyers Academy. Each module brings something new, and shifts my way of looking at a process. Although the Academy is over zoom, it never feels impersonal. The cohort of learners are so willing to help one another and to offer encouragement. Jennifer has really created a nurturing learning environment. Jennifer and Tristin are always available if a question arises and you never have to wait until the next meeting to raise a question. I am so excited about creating my own work portfolio and plan on filling in with more of my own recipes based upon what I am learning. - Joanmarie S. (USA)
