Berry Fun Yarns are dyed naturally, without the use of toxic chemicals. The colors are coaxed out of the beautiful plants and flowers (or even coffee that Grandpa drinks!) that fill the fields of Firefly Berries. We do purchase a small amount (less than 10%) of our dyestuff or natural extracts from trusted U.S. dyestuff companies, as there are a few colors that are we are unable to grow in Minnesota.
Dyeing yarn naturally is different than using acid dyes in many ways, but the most striking to the dyer is that naturally dyed yarns are highly sensitive to the pH of the water used both in the dyeing and washing process. A slight change in the pH of the water can yield an entirely different color. Because of this, we recommend handwashing all Berry Fun Yarn in cool or tepid water with a pH neutral soap like Eucalan. Once we dye the yarn, we do wash every hank to assure the dye has both set and is easy for the customer to work with. We also recommend storing your yarn and finished products out of direct sunlight.
