I found this book very useful and found the explanations and instructions clear and well-explained. I especially liked the advice section for when things go wrong. It has many good ideas which can be extended and personalised. My only problem is that, as in many of these books, the items and materials have American names that are not used in the UK and Europe and are often very hard to obtain here, so, frustratingly, many projects cannot be attempted. I would like to see alternative products listed, and, as in some books, suppliers listed in Europe and other continents, not just the US. Please, American writers, be less America-centric.
