Well I don't know if it's Kate & William's influence but actually I had the idea a long time ago. Let's make our pupils organize a wedding. They could create a book presenting the different aspects of the wedding they've organized.

They can even imagine the couple (imagining a wedding between Darth Vador and Leia Organa could be fun!), the family, the recipe for dinner, the animations, etc.

Here are some links that could give some ideas to organize it. Google even proposes tools to help the wedding planner:
