You make the book a lot of fun - at least disappeared daughter in the room, and came after a relatively short time with the first 'product' back.
It is positive that finally other handicrafts are excited than usual and that the things also are reasonably suitable for everyday use (eg the wallet).
It must be remembered that the book is written in English - you should definitely possess advanced English skills. Moreover Ducttape is not as readily available in Germany and, if applicable. expensive.
Basically, the book is about from 10 years to use up, at least when the children or parents enough English can. However, one should professing gross motor Rikern go something at hand - Ducttape is tough and sticky and who is at loggerheads with sharp knives, can then try relatively quickly whether Ducttape is also suitable for wound closure ...
Since Ducttape is really sticky, it sometimes takes a helping hand to prevent it from sticking somewhere where it should not stick, but all in all (assuming language skills) for children from 10 suited the book.
Actually, the book deserves 5 stars
