I'm rubbish at colours 
I have some full balls of Stylecraft DK in khaki, stone and sage that I bought for a project and changed my mind. I think I may also have a full ball of bottle green too. I want to get another colour or two to go with it and make a small blanket with it - either in ripple or harlequin stitch. Would fondant go (if I don't use the bottle green) or should I stick to a green/brown palette? Any other suggestions? My local yarn shop has a decent range of colours.
