An art teacher friend has told me that WH Smith sell System 3 Acrylics, which he says are far more hard wearing than more expensive acrylics and more workable than any car body paint. So I'll go for that. I thought I'd paint a huge sunflower down the middle of the case (I have them in my garden in the summer and adore them). But before I start, anyone like to try and convince me to do something else?
