Consciously Crafted Fibers Blue Sky Fibers uses natural fibers to create beautiful yarns that are designed to inspire and delight fiber enthusiasts of all types as well as being environmentally ethical. They work with alpaca and sheep herders in South America, where the animals are raised and cared for as they have been for centuries. All of their cotton is GOTS certified organic. And the yarn is dyed in large batches using low-impact dyes. While not organic, these dyes are formulated to have a lower impact on the environment than traditional chemical dyes.
