These technique for making these paper was thought lost until recently.
Dutch Gilt or Brocade papers are a type of highly decorative paper whose origins date back to 1700s Europe where they were used as covers for children's books. The pattern would created by blocks of wood or metal, or by engraved rollers. The gold leaf would be transferred to a pre-coloured background using glare, a type of sticky size.
These papers were probably made in Germany and exported via the Netherlands and the term Dutch refers either to the exporter or may be a mispronunciation of Deautsch.
