In playing around just before posting my last post, I seem to have inadvertently clicked on 'apply to blog' instead of the 'lets have a look' button.
So the blog looks a bit different! Not too much though. I have been thinking about making it look a bit more spiffy and colourful recently. I quite like how this looks so I may leave it, but if I have second thoughts I will be asking techie guru Husband if he can help me sort it out. And no, I don't think I have a backup of the original template.
Moral of story - don't try and be clever when really tired.
