I have painted a boat on it. I used a piece of acetate on a white sheet of A4 (so I could see what I was doing), drew roughly what I wanted after looking at cartoon type boats using google image and then cut them out. I then used felt tips in whatever colour I was using to draw round the acetate and painted. It needs another coat at this point, but I am happy. I was going to paint some lighthouses round the sides but am not sure.
