When I first got this book, I chose a few things to do and got all the materials ready, and my two grandchildren, aged 7 and 4, (and my son) enjoyed making things with me. Now the 7 year old is into it every time he comes, making something himself, and has a list of things he wants to do next time. He reads out the instructions to me on the tricky bits, but often can manage to do it all by himself. All the things that you make "do" something and I think this is why I love it. Even though the 4 year old can't yet make these things alone, he can help and play with them afterwards. They are simple, but fun - the 4 year old particularly loves the "helicopters" and spends a lot of energy rushing up the stairs to drop them down again. The illustrations and instructions are clear and the items you need for each project are listed at the beginning. Most of the materials needed are things you will have around the house or are easily obtained. It's a great help to adults who are not naturally "crafty"and most of the ideas don't take too long for those with a short attention span. It also leads to quite a lot of "how" and "why" questions, which is stretching my brain as well as the kids'. I like it so much that I am thinking of giving a copy to a couple of my nieces for Christmas as they have children of a similar age and I am sure they will love it. My only disappointment is that it is at a higher price than when I bought it, but I still think it is great value for money.
