Description from Knitty.com:

Edgar the edgy scarf is my latest approach to the possibilities of one or two balls of self striping yarns, showing off all their beauty and brightness.

One ball of Noro Silk Garden or Noro Kureyon knits up to a cravat, 43 inches long. If you'd like an extra-long Edgar, 2 balls will end him at 85 inches. If you want him medium (60 inches), one and a half balls will do.
