This beret is knit flat and then sewn up. The designer recommends using a DK weight angora blend yarn, perhaps adding some novelty hand dyed to the mix. <p>Possible yarns: RYC Cash Cotton DK, Fleece Artist’s Peter Rabbit, or Sublime Angora Merino. A plain DK weight yarn will also work. Yardage is estimated: the pattern just says you need 50 grams of DK weight yarn.
