I am pleasantly surprised by this book. There are only a few comments, explanations are mostly visual. This method by example is efficient and provides fast correct results. Moreover, with the abundance of examples, it is then easy to create his own letters by combining the elements differently. The delivery was fast. The icing on the cake, a criterium is inserted into the binding; it only remains to find the paper. The book also contains sheets of stickers. This book is aimed at teenagers to adults. The colors are sparkling and a naive drawings and everything gives a beautiful book.
