Costume Designer John Bloomfield worked for nearly a year on the mini-series. He spent three months doing basic research at the National Portrait Gallery, Windsor Castle, and various libraries, going through books and papers, and studying paintings and drawings, especially those by Hans Holbein. Apart from the sheer number of costumes involved (three hundred, including twenty-five for Henry), the real challenge was to re-create the richness of court dress. This was accomplished by using screen printing methods with paints and resins on cheap heavy materials. Embossed fabric patterns were achieved by drawing on the basic material with fiber pens, then painting over it.
