We have put together a terrific kit of local Corriedale to make Bernie's iconic mittens.
You can find patterns on Ravelry to knit a version of Bernie's mittens. His original mittens are made from recycled sweaters.
Each kit consists of four colors of worsted weight yarn. A full skein of medium brown and half skeins of white, dark brown (black) and light brown. Total yardage is about 500 yards.
