Hello, I’m afraid Heather can’t come to the blog right now as she has developed an unfortunate addiction to educational physics games. In the interests of your health, do not click on this link, or this one, unless you have already finished all your Christmas knitting, or have managed to work out how to knit and play games at the same time. Heather should return soon, and is hoping to have some actual knitting progress (!). If you would like to leave a message please do so after the tone.
