We’re not talking themes like those, that are so beloved by little girls, ones based on a favourite book or cartoon character. But more a general spirit or decorating hook to help shape the kind of space you’d like to create. Is she a keen book worm, musician or nature lover?
Do open shelves with collections of art postcards or breezy seaside stripes reflect her character? Any scheme benefits from an overarching theme to help you work out what does – or doesn’t – fit, and stop it running off in many directions.
It can simply be a love for bold colours or washed out or Nordic inspired bedroom. Find some element like wood blinds to use as a central idea and it will be easier for the rest of the ideas to take form.
