Hey Chris! I use Staedtler Pigment Liners – usually I use a 0.5mm for thicker external lines, a 0.2mm for my crosshatching, and a 0.3mm for details and decorations. Then I scan them and convert them to vectors in Illustrator (so that I can resize them however I like) and add a grid. So, pretty low tech, and nothing fancy other than some fineliners that I happen to like 🙂

I’ve only just come across this amazing site when I was looking into Island Campaigns for D&D. These posts have been fantastic and I love your thought process and maps. I was wondering, how do you draw your maps? Do you have a particular tool that you use?
