April 1st (cont) 
          In order to work out where I should put my fluorescent paint and what 
          colour I should use, I took a photo of the completed cloth (before the 
          fluorescent was applied) then scanned it into my computer and, using 
          a graphics program, made the picture a dark blue. I then put a separate 
          layer on the top and drew in my coloured fluorescents. Once satisfied, 
          I took a copy of this graphic with me and worked from that when painting 
          on the fluorescent paint. NOTE for the lighting designer - perhaps the 
          most interesting wow factor of this cloth is the 'invisible blue' windows 
          on the skyscrapers which should "miraculously" appear under 
          UV light.
