• Review (by Ondřej Zatloukal):
  “During the last three days in Prague there was a workshop Match your infill, which I had the honor to co-organize. We were joined by Rita Udina, an excellent Catalan restorer and lovely person, who gave us all her experience about powdered cellulose, mould casting, dyes and colorants, papers pulp etc.
  The great thing about the course was that the techniques and procedures presented are really practical and find a place in the studios of all participants.
  So if you ever have the opportunity to attend the course, don’t hesitate, it’s a great opportunity!
  Thank you Rita!!!! :)”
