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
Payment: Half down is due prior to processing; remainder due prior to delivery of finished product.
Minimums: Individual yarn orders less than 2 lbs incoming weight will be charged at the 2 lb rate. Orders without yarn (roving, rug yarn, and felt) will have a $100 minimum on the total order.
To respect our customers' privacy, neither the public nor mill customers are permitted to enter the mill production area unless participating in a mill tour. All tours must be scheduled in advance. If you would like to take a mill tour during a scheduled fiber drop off day, please contact us in advance. 

We are now offering rug-making services. Prices are outlined in the Services & Pricing document on the right.

Education is also a priority of the Mill. We offer classes through the year and welcome inquiries about all things fiber and processing. See our Events Page and Watch our Facebook page for upcoming classes.
