We've just added a new base yarn to our lineup that we're extra excited about: Merino Twist Eco.
The wool is this yarn is certified organic by GOTS, ensuring that it meets social and ecological standards in everything from the care of the sheep to the working conditions for farmers to the superwash-like treatment of the wool. (The yarn itself isn't certified organic due to the 20% nylon content.)
Merino Twist Eco has the same 8-ply construction as our trusty Merino Twist, making it a great choice for hard-wearing items like socks.
