Each member of the Royal Family has a cypher, rather like a monogram, using initials and often a crown. Here is the royal cypher of Queen Elizabeth II for the children to colour in. We also have a poster if you want to look at the correct colouring.

This simple lettered God Save the Queen colouring page will be fun for younger children, and can look extremely effective when complete, whether they choose royal purple colours, something completely different, or traditional red, white and blue.
Here's a colouring page of Windsor Castle to print. The Queen's favourite royal weekend residence (and where she now lives almost permanently), Windsor Castle is also the oldest and largest occupied castle in the world!
If I was a queen, this is exactly the sort of throne I would like to sit on - grand and imposing, but still very comfortable! What colour will it be? We have a more detailed throne colouring page for older kids here.
