Adventures in Multi-coloured Yarn

I'm loving multi-coloured yarn at the moment. I love the uniqueness of it and how different it looks. It's fun, quirky and makes the simplest design interesting.
I've been making lots of multi-coloured coasters, some that are available in my etsy shop, I think they're cute, I made some for my coffee table too.

I'm out of that yarn now, I think I'll definitely have to buy more at some stage and see what else I can make.
Any ideas??
