Almost everything. Book restoration is a little-known profession, it emerged in the 1970s. People don't imagine that we have scientific knowledge, like doctors and engineers, we have to make real diagnoses. People often imagine that we are pure craftsmen.

Yes, I was lucky enough to learn from several different masters. At the workshop where I worked in Paris, Jacky Vignon trained me in the art of bookbinding. I was impressed by this man of great elegance and humility. He was very pedagogical in his way of teaching: he did not keep any of his secrets.

Absolutely, I take a lot of pleasure in sharing knowledge. I give courses on papermaking (at the Ecole des Beaux-Arts in Avignon) and each year I welcome a student to my workshop. I then help them to find internships, it is important to follow them beyond the diploma, to be a reference point for them.

My daily life at the Moulin du Verger, making paper. The mill had not moved since the 16th century. Every day I was repeating practices that have not changed since the 12th century. Being on a historic heritage site and working with the same methods that have been used for 400 years was special.
