One Row Scarf

I'd been looking for a scarf pattern for a while, and stumbled across the Yarnharlot's One Row Handspun Scarf. It looked like fun, and I thought I might want to use it for a silk scarf I had planned (plans have since changed). So I grabbed some yarn I had lying around, cast on and started a swatch.
Things may have got out of hand. I now need to order two more balls of Patons Symphony yarn so that I can have a scarf.
It's not handspun. It's not even a natural fibre. But I like it.
