It took some trial and error to get all the elements in reasonable scale relative to each other, and balanced in a way that would flow and make sense with enough spacing including room for the text. It was fun drawing the cool cutting machine (I wanted to write hand-cutting as it's operated by pulling the lever, but that just sounds bad!).
The day of the actual chalking involved a projector, with my line drawings changed to pink so I could see where I was, and joining the whole picture up from two halves as it was too wide to project as one image.
This was a fun job, working for a lovely bunch of guys making a truly delicious product!
