The design is very close to the tapestry and must belong to a late stage of preparation. Many of these small chalk drawings were made for the San Graal series. When the composition was fixed it was blown up photographically to make the cartoon, which Burne-Jones would then work over again, paying particular attention to the heads and hands. Some of these cartoons are in the William Morris Gallery. It was left to William Morris's chief assistant J H Dearle to design the ornamental details such as the foreground flaowers, and the weavers themselves were allowed a measure of latitude in the choice of colours and shading. Morris prided himself on having workmen who were 'artists, not merely animated machines'.
