When this went on the list I was envisaging a day out in the forest en famille, good wholesome family fun, fashioning windbreaks with rows of sticks, a grassy reed roof, a carpet of moss… that kind of thing. A day spent creating a thing of magnificence, all from the rich resources that nature has to offer.

But then opportunity knocked, and with less than 2 months to go, I opened the door with alacrity. It was a bright sunny day, we were playing in the garden, the kids had a friend round, I was desperate to knock off a few of the 100 but couldn’t leave the premises. Then suddenly, ‘Can we build a den mummy? In the garden?’ Indeed we could! Me and the youngest spent a happy half hour, fashioning an ingenious den. Two benches, a load of old bedding, some stones to hold it all in place; a carpet of hessian sacks, and then filled to bursting point with all the dolls and soft toys in the house. Perfect. Add a jug of juice and a few chocolate biscuits and that is a happy playdate, and can just about (if readers are minded to be generous) count as one of the 100.
