These rich blue toned variegated super soft merino mittens are done in a simple stockinette stitch to show the subtle, hand-dyed highlights. This yarn, "Rios" is named after the four major rivers in Uruguay: Rio Cuareim, Rio Uruguay, Rio de la Plata, and Rio Negro. Each river is represented by one ply, which twist together like winding rivers. This yarn can be machine washed in cold water.
