Coastline Sport*
*Part of the Sea Change Fibers trunk show at String Theory through May 8, 2026. No exchanges or returns are permitted for trunk show purchases.
Sea Change Fibers is a hand-dyed yarn business founded in 2016 by Sarah Pederson in Portland, Oregon. With a focus on sustainable and locally produced wool, sourcing from climate-responsible producers, they are known for vibrant tonal colors and commitment to sustainability, climate health, and social justice. The brand began as The Dye Project and has since moved to a home near Monterey Bay, reflecting a deep connection to the Pacific Northwest coast.
Coastline Sport is all about softness and drape! Light enough for mid-season, and even Summer, wearables, these tonal solids let the silk really shine.
