dürer probably did not cut any of the woodblocks himself. this was a job for experts. but he had designed and cut woodblocks for woodcut as part of his training in wolgemut's studio, and he had seen many carved and painted altarpieces made in the studio. this means he knew what could be made into a woodblock print, and how to work with the expert block cutters. dürer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block. either way his drawing was destroyed when the block was cut.
