22. This is now done. Now you can start adding your own things to the edges. I went back and added an outer glow of black to the “land” layer as well as an inner glow of black. I did the same for the mountain line (not the little hatch lines, the original fat line layer) but with a smaller size glow radius. You can use the empty space for doing inset maps of islands or cites or add clipart or whatever. Just make sure that anything you add is genre appropriate (no spaceships). When the map is all done, add your favorite torn edges/burnt edges/ripped edges border and add in some distress, folds, scratches, grunge and whatever else.

Happy mapping to all and to all a good map.
