Last September I bought this book by Rebecca Burgess. She visited 3 natural dye artist across the US and in her book showcases 3 dozen common plants that yield striking hues. One of the places she visited was Hillcreek Fiber Studio in Columbia Missouri only two hours from my house. Intrigued by the process detailed in the book, last October I enrolled myself and my wife in a 2 day class that was held last weekend. It used Missouri Wild Plants which we collected and processed to dye cotton, wool and silk. We had a blast and learned so much and yes I was the only male there. Carol Leigh Brack-Kaiser owner and teacher of Hillcreek has travelled the world studying natural dyes and dying processes and is well respected in the field. She is a weaver and has a wonderful shop full of goodies associated with weaving, spinning, knitting and dying. Well worth the trip if you are ever in the area.
