Natural Fiber Processing Mill in Sunnyside, Washington
Located in the sunny Yakima Valley of Central Washington, Spring Harvest Fiber Mill is family-owned and operated. The Mill’s primary goal is producing quality fiber products, including soft, bright yarns in several weights, roving that is made for hand-spinning, and felt products.
To submit fiber for processing, please download our fiber submission form at right. One form must be submitted for each batch of fiber.
We are now offering rug-making services. Contact us for details and prices.
Education is also a priority of the Mill. We offer classes through the year and welcome inquiries about all things fiber and processing. Watch our Facebook page for upcoming classes.
