My dad have the birthday and this cookies is for him. His moustaches are grey, so I colored my icing with grey.

I find on internet the pages down and this was my inspiration - the template for the bowler hat. I cut out one from a paper, put this on the dought and cut with a knife. Here is the finished plate!
