Brunel hat modification.

This hat has caused some fun at Steampunk choir when we sing about Brunel and his massive hat !! It now has a steam train added.
I now want to add the original Great Western Railway logo on the front of the hat, which will take some careful work with synthetic foam and a scalpel !!
My other hat project is a hat to go with our song about Jules Verne to the Can Can tune from Offenbach This is proving more difficult than anticipated as I want a submarine to be somehow submerged on the hat , and in an ocean !!
