Crochet

I've been thinking about starting a new project.

I was really inspired by the look of the shawl in this blog post.

The problem I'm running into is finding yarn that will fade from one colour to the next gradually over the span of 1000m. All the skeins I'm finding in my local shop vary in colour a couple of times in just 300m, or much less gradual than that.

If such a product can't be easily found, I suppose I could buy several skeins, cut them into many long pieces, group those pieces by colour, and then wind it all back up again? But to me that sounds like a crazy idea.

I'm the first to admit that I'm new to crochet and I'm still just shopping at the local general craft store. That's why I'm posting. I'd really appreciate any advice that more experienced folks have on finding what I'm looking for.
