Whirly windmill

We were at an eco house-building/renovating trade fair today. The plan was to go while Matthew was at school, but as he was off he came too. And good news for him that he did. We hardly walked past a stall which didn't have boiled sweets or bonbons. So him and Nell crawled about the woodburning central heating stands and got up to all sorts of mishief in the wool insulation. They got a balloon and a whirly windmill too, and here they are both blowing.
