Guy and his best mate Mave decide to give their historic narrowboat a makeover. They learn about the most influential British interior designer of all, William Morris, while trying to stick up wallpaper he originally designed.

They then master the fine art of narrowboat painting, and attempt their own version of the traditional decoration of castles and roses.

Finally, Guy visits Paradise Mill in Macclesfield to learn how to weave silk for an interior decoration, using what is considered to be one of the first computers.
