Caroline @ Coastcard: I decided that a (re-purposed) polystyrene pizza base would make an ideal 'canvas'. I had been collecting pistachio nut shells, so I wanted to incorporate these, especially as mice and nuts seemed to go well together. I was given some pet fur from a comb after a grooming session, which I added to a bit of sheep's wool from a fence. In the end, this pizza base did not form the final picture, but it was a key stage along the route. I hope you like the mice!
