DIY Wool Processing: Closed-Loop System on a Regenerative Farm

This case study from a Midwest permaculture operation documents a full DIY pipeline for wool processing, achieving closed-loop self-sufficiency. Starting with sheep shearing using homemade clippers from repurposed electric shears (tensioned at 1/16 inch), the process yields 10 lbs raw wool per animal. Washing employs rainwater and mild soap (1:10 ratio) in 140°F baths, followed by carding with hand-built drums from bike wheels and wooden frames (40 tines/inch density). Flax processing integrates scutching boards from oak planks and hackles for fiber separation. Spinning uses drop spindles or repurposed bike-wheel wheels at 50-60 twists per inch for worsted yarn. Natural dyeing employs on-farm plants: madder root (1:1 weight ratio, alum mordant) for reds, indigo vats (fermented leaves at pH 9) for blues, yielding colorfast results. Yield metrics show 10 lbs raw wool to 7 lbs finished yarn, with 30% loss minimized via thorough skirting. Startup costs under $200 include $50 for bike parts, $30 for dyes. Resilience benefits proven during supply chain disruptions, producing 50 yards/month clothing. 2-year follow-up reports durability: socks wore 18 months vs. 6 for commercial. Blueprints detail carder assembly (18x24 inch frame, spring-loaded tension), washing stations with drainage, and storage in cedar chests preventing moths. Photos illustrate each step, from fleece grading (remove vegetable matter <5%) to plying (2-ply at 12 wpi). Ties to regenerative farming via pasture rotation boosting wool quality. Practitioners gain concrete blueprints, metrics, and troubleshooting for scalable fiber independence.
