Many years ago, when looking for our first home, I was astonished at the multitude of decorating ideas I came across. Some, I’m sorry to say, looking like they’d just come out of a 1960s movie set. (No offence to anyone who is a fan of the shell-shaped green sinks brigade. It just wasn’t my thing!)When we finally made the deal and bought our first home, a railway cottage, we let rip with the paint brush as we reckoned Salvador Dali himself must have lived there.
