I did some research online about medieval businesses in order to get an idea of what a medieval butcher shop would contain so that the plan would at least have a level of believability. If you have some pictures of a real medieval building I would most definitely like to see them! That's one of the drawbacks to being such a fan of architecture and living in the western United States: We really don't have any "old" buildings compared to Europe.

The hatching was done by eye. I've always preferred a nice tight hatch over a solid fill since I think it not only looks better but saves on printer ink as well. I have been hatching my drawings for years and through practice my lines have become pretty uniform. I'm definitely not perfect, however, and if you look at the largest version of the drawing you will see that some of the hatches are spaced wider and narrower in places. I think the minor imperfections like those are what give hand-made drawings their charm
