Yarn for my next crochet project

I've just finished crocheting another skull scarf (in green this time) which should shortly be going off to the person who asked me to make it. I'm now moving on to my next project, which is a ripple-striped lap blanket for my Dad. (I'm using the Attic24 smooth ripple pattern and I'm loving it!) It will be a combined birthday and father's day present. I'm using these colours. I'd prefer something brighter, but I think these will suit an elderly man better. He is 92 after all!
