I'm sure I have one or two more skeins which would work colour-wise with these. That's once I find them? I'll bag these up and put them aside while I work on the previous batch.
I'm working on a different idea for the blue, green and mauve yarns. It's a technique which has been rumbling around in my head for a while now. It's called helix or spiral knitting. I first saw this in Montse Stanley's Knitter's Handbook. I have the 1993 version. Techknitting has two posts on her blog about it and an article in Interweave.
I've also seen many hats and sock produced with this technique.
Here's a few examples:
It's a way of blending yarns in single row stripes. I'm off to do some more swatching, silhouette consideration and marinating for the first batch of yarn.
