Wembury Blue is a gorgeous, eco-friendly double knit yarn from Devon-based Jolly Good Yarn. The yarn is created by upcycling left-over textiles from manufacturing, as well as clothes that may have otherwise gone to landfill. This versatile, soft yarn is made from at least 80% recycled cotton and 20% other recycled fibers.. It is ideal for crochet, knitting and other smaller projects. Each ball weighs 50g and provides approximately 85m of cord. This DK weight yarn works best with 4mm (US size 6) needles and hooks. Due to its recycled nature, the shade may vary slightly over time.
