Alissa Allen founded Mycopigments in 2012, as a program to bring mycology to fiber artists and fiber artists to mycology. Since its inception, she has led hundreds of students, in three countries and twenty-five states, through the steps of exploring their regional mushroom and lichen dye palette. Alissa got her start in the Pacific Northwest and has been sharing her passion for mushrooms for over 15 years. She has written articles for her website as well as Fungi Magazine and Fibershed. In 2015, Alissa created the Mushroom and Lichen Dyers United discussion group and the Mushroom Dyers Trading Post to mentor, connect, and facilitate discussion between her students. These Facebook groups, along with her prolific workshop offerings have brought together a vibrant community of over 11,000 members. Though her focus is centered on teaching people about their regional mushroom and lichen dye palettes, her overall mission is to inspire people to engage more deeply with nature. It is her hope that with engagement, commitment to care for our planet will grow exponentially.

Katherine Ferrier is a poet, dancer, maker, teacher, curator, and community organizer, and has been the Director of the Medomak Fiberarts Retreat since 2018. Her research grows out of a deep practice of paying poetic attention to the world, and lives in the intersecting communities of movers, makers, writers and activists. A self-taught quilter, she has improvisationally designed and constructed nearly 100 quilts, drawing on her years of study, both formal and independent, of movement, poetics, painting and architecture, among other forms. She regularly teaches and performs throughout the US and abroad, and believes in patchwork as a radical practice of being patient, saying yes, and making space for everyone at the table.
