Meet Sarah

Sarah Tremaine


I grew up in New England, close to the forest and the sea. I moved to the foot of the Blue Ridge Mountains, 43 years ago, to study environmental sciences, and 20 years ago, I shifted gears and began following my passion for designing Wearable Art using local plant materials for eco prints, natural dyes, fibers, and fabrics. It is so important to me to create and hand-make stylish, comfortable clothing, accessories & home decor that are flattering & healthy for you and for the planet. I have been teaching in person since 2010 and online since 2020. I find I can be so much more complete in my online Workshops since students have more time to absorb the material. I now provide my in-person students with access to my online material & they love it!

What Former Students are Saying...

“The pre-workshop materials were very comprehensive. It was great to have additional resources! Sarah’s teaching was very organized and concise with demonstrations. The class handouts were very helpful and the pace was great!”


“I had the best time attending one of Sarah's dye workshops. Sarah is a great teacher, she explains things well and invites you to observe every part of the process. The loveliness of the workshop still lingers for me and has inspired me to continue incorporating dyeing into my life.”


“Sarah is a great teacher! Her instructions are clear, process well defined and creativity encouraged. I appreciated that I was able to create four lovely silk scarves during a one-day workshop - and that she provided written instructions and supply sources so that we could easily continue with our new skills at home. I’m looking forward to her online classes!”
