Taking a short break from hats. Phew.
I did something with lids and coasters some time back and still have a stack of tin lids for recycling. I was thinking tree decorations?
I just made up some circles and kept changing the colours, although you could adapt a nice coaster pattern (like the one Janette used here: http://crochet.about.com/od/vintage/ss/aa052606.htm)
Back soon x
