Windrush Farm Fiber School holds classes on a working fiber farm with sheep, goats, cows, alpacas, llamas, pigs, angora rabbits, and chickens. In fact the classroom is in a part of the barn close enough to hear Rudy the Rooster talking to his hens or the happy cackling when one of them lays an egg. The 25 acre farm is in the beautiful Chileno Valley just outside Petaluma, California about 1 hour north of San Francisco and just west of Napa and Sonoma Valleys. Each class includes a tea and cookie break and a walk through the pastures to meet the fiber animals and greet the guard llamas. Ever feed a sheep? A class on Windrush Farm is a truly unique experience to explore the world of fiber surrounded by the land, animals and the fiber they grow.

2021 Fiber Classes


Fleece to Garment Series

This exciting class series offers the unique opportunity to go from fleece to finished garment. The series provides a wonderful way to learn the process hands-on, have personal instructions, a community of other fiber enthusiasts to be around, and set deadlines to help complete your project (we all have a few unfinished projects in the closet).

This class is designed to challenge intermediate and advanced spinners with the adventure of choosing a fleece, preparing it for spinning, discovering the merits of that fleece, and finally matching it to a garment design.  Students in this class must be able to spin a continuous thread and know how to knit, crochet or weave.  We offer beginning and intermediate spinning classes in the fall for those needing to learn or improve their spinning skills in order to take this class. 

January 30th, Saturday, 10am to 3pm – Shearing and Fleece selection – Students will see the shearing, pick their fleece, and then learn about parts of the fleece, how to skirt, and how to match the qualities of that fleece to a garment. 

February 7th, Sunday, 1pm to 4pm – Scouring Fleeces & Designing Your Project – We begin the process by learning how to scour (wash) the fleece in the class.  We will examine a variety of knitted samples in different needle sizes and look at different prepping to begin to plan the design of the garment.  We will have 4 different designs to choose for your garment.

February 21st, Sunday, 1pm to 4pm – Prepping Your Fleeces to Spin –Spinning with curls, spinning woolen, or spinning semi-worsted are techniques that have different effects in the finished garment.  What works best for the fleece?  Will you card or spin from the lock?  We look at how the prepping of the fleece influences the design of the garment.

February 28th, Sunday, 10am to 3pm – Carding & Designing Your Yarn – This class will work on carding your washed and prepped fleeces. You will begin spinning and work on creating your yarn for your specific project.

April 11th, Sunday, 1pm to 4pm – Project In Process – Bring in your in-progress project.  Are you stuck? Need encouragement and feedback?  This class will share all the projects and offers specialized help for completion of the garment.

May 2nd, Sunday, 10am to 4pm – Spin In & Fashion Show – This is a great way to end the class. Hang out for the day spinning and knitting in the morning. After a yummy pot luck lunch everyone will show off their projects, no matter how far along. This is open to all spinners, knitters, and friends.
