There really is no excuse.

I just realised how much cold air is coming in through air gaps round the front door (not to mention the whacking great catflap which blows open with the smallest breeze). I had a brief dig around in Tim's wardrobe, having remembered that we have a thick door curtain (bought 8 years ago) in there. Partnered with some net curtain wire, I have hung the door curtain over the drafty door.

The difference is palpable.

Why on earth didn't I do this years ago?
