nesting material

In your latest(lovely) magazine, under "five things to do" as nesting material you include hair from a hairbrush. A word of caution, two years ago a horrible thing happened to me, a blue tit strangled it'self trying to take a long human hair into the nest hole. It was one of my hairs and I felt awful about it. I think perhaps human hair is too strong. However they love the combings from my dogs and take it almost as soon as I put it out, so maybe that makes up a little.
