This drawing started out as an A5 hatched with a (scratchy) 0.35 Rotring. This was enlarged to A1, hatched again, this time with a 0.18; enlarged again at 200% to make 4xA1s, hatched again, again with the 0.18; then, finally each A1 was split into two A2s and each enlarged to A1, making 8 A1s which were hatched one last time with a variety of grey and white pencils.
