from Crochet Me site:

I have poker straight hair, so I’ve always wanted curly ringlets that I can twirl around my fingers absentmindedly as I chatter away. Unfortunately, curly hair looks about as natural on me as a goatee. So I decided to make the next best thing, a curly scarf. And that’s how this scarf was born. The sentiment behind it’s conception, it’s grape vine-like curl, and the two-tone berry colour all led to it’s name: Sour Grapes.
