I actually first discovered this book in a book fair in France in it's original format (Mme de Dillmont wrote a number of works for DMC - the needlework supplies manufacturer), and was fascinated by the sheer breadth of information it contains. It is undoubtedly the last book still published today to deal with a great many techniques which were once widely known and used. Although it may seem complicated at first, instructions are detailed and easy to follow and the hundreds of beautiful and varied projects contained in the book are a welcome change from the very standardized fare available in most current needlework books. Originally written for beginners, the decrease in general knowledge of and expertise in many techniques means that this book is as perfect for advanced needleworkers as for learners.
The only possible problem with this book is that you'll never need to buy another needlework book again!
