I wish it was that sophisticated. I 3D printed a stencil or jig to line up the edges and use a razor knife on my kitchen cutting board. It works well enough. I did originally consider national parks or cities. I came up with it on vacation and saw some cities have their own distinctive stickers. The problem I ran into was details are hard to resolve with the art style I’m using. Words are even worse. I did a series with US states before this. I might have to revisit this when I’m tired of hex FOSS.
