Wrapped-up warmth

SIR – Far from taking offence at advice from various energy companies, I went out and bought more merino wool socks. I already eat porridge every morning, and, while I don’t have a pet to put on my lap, I find that wearing a fluffy onesie and wrapping up in a fleece rug does the trick.

If that isn’t enough, I recommend a rib-cage draught excluder, which I crochet. It is a 5in-wide sash belt with buttons down the side worn around the midriff on top of a sweater. It definitely keeps the body warm. Andrea Bates
