BC Garn is the brand with the most GOTS-certified yarns in the entire industry. Fourteen yarns are already fully certified, meaning they are verifiably produced according to strict animal welfare and environmental protection standards. Furthermore, the GOTS seal guarantees fair wages, occupational safety and health, good working conditions, and social responsibility. All of this is audited annually.

BC Garn stands for natural and sustainable yarns that actively contribute to a sustainable and ethical fashion industry.

The traditional Danish company BC Garn was founded in 1972 by Bo Carstensen, who came from a family of weavers. The focus has always been on developing yarns from natural fibers in a wide range of colors. In the spring of 2018, Marianna and Bo handed over "their baby" to Britta and Carsten Kremke, who continue the yarn, color, and design range in the tradition of the Danish founders.
