The School of Athens
When a final composition was achieved, scaled-up full-size cartoons were often made, which were then pricked with a pin and "pounced" with a bag of soot to leave dotted lines on the surface as a guide. He also made unusually extensive use, on both paper and plaster, of a "blind stylus", scratching lines which leave only an indentation, but no mark. These can be seen on the wall in "The School of Athens", and in the originals of many drawings. The "Raphael Cartoons", as tapestry designs, were fully coloured in a glue distemper medium, as they were sent to Brussels to be followed by the weavers.
