Thanks for the help Sue. Here is the finished map. Some lines are still there when you zoom into the map, but for the size I use in Roll20 you can't see any lines and that will do for me.

This is the Moathouse dungeon from The Village Homlet classic module.

This is my map for a Theros game set in ancient Greece.

This is a fantastical version of the Late Permian (circa 250 million years BC).

I found Sue's brilliant style for free and just had to draw a map with it.
