Lamb's Pride superwash sport weight 3 ply wool in a beautiful, subtle deep aqua teal. Sadly, it is discontinued. I have this and a few other colors.
Machine washable, but do use a very gently cycle. Personally I always handwash my handknits, and recommend that because machine washing involves a lot of rubbing against other fabrics, resulting in more fuzzing, and loss of stitch definition. Mothproofed, and made in the USA.
Color Dragonfly; lot 002
