I finished a baby blanket for a friend today and love the colours in it - I can't resist using rainbow colours, they all look so much better together.
The blanket got me looking for other rainbows. Here's a button picture me and Me CB made last year using my button stash.
And a yarn rainbow (this is what happens when I'm left alone for 3 minutes with a basket of yarn and a camera).
Now I must find more!
