It really is!! And the heater I wanted to order from John Lewis is no longer on their website, though I don't think it was a sale item :(
That's the bad news. The good news is that the weather forecast is showing it as warming up a bit on Sunday - which I will believe once it happens! It's misty here, so no sun to warm us inside, but it is better than the forecast. Another downside is that for some reason I always feel I want to eat when I'm cold .... which is a big no-no if I want my projects to succeed.
