3mm Heavitree Black is a gorgeous, eco-friendly single twist macrame string 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 cord is made from at least 85% recycled cotton. It is ideal for macrame, crochet and chunky knitting projects. The thread is made up of 12 soft fibres, twisted up into the style known as 'single twist'. Each ball weighs 125g and provides approximately 50m of cord. Due to its recycled nature, the shade may vary slightly over time. It is recommended that you purchase enough yarn to complete your project.
