I started creating fantasy maps for my Dungeons and Dragons campaign by hand many years ago, before computers made it into the home. It was easy to draw rivers with pen and ink and the maps held as much detail as one took the time to put in them. We soon learned less is more in most cases.
Today with modern computer tools I started making maps again, for my online Dungeons and Dragons campaign. Who knew? Making maps for online requires a different set of tools, if you want the detail beyond the pen and paper variety. But creating rivers elluded me. Until I found the secret.
Creating realistic rivers is a chore if you don't have the right tools. Learning how to use those tools is the important part. Using a pressure sensitive drawing tablet is an easy fix to this problem but I don't have one. I found a solution. I will be using GIMP 2.8 for this tutorial because it is easy to learn and free to download, so anyone can follow along.
