This gorgeous sweater duster was handknit in the 70's. Super soft yarn, possible mohair or angora, I can't be certain. Gorgeous quality and condition. Warm shades of browns and blues. Reminds me of the Southwest. This will fit up to a 2X, however, please see the measurements below for a proper fit.
