Multicoloured crochet "twist" scarf

My next project is to create a twist scarf, its something that I've been meaning to do for a while but not got round to it.

I'm using some wonderfully colourful yarn from patons, Fairytale Colour 4 me DK - its the orange, green, yellow & purple one.

The scarf is underway, and here is progress so far.....

I love the way something as simple as increasing the stitches can create such a lovely texture.
