After seeing the $600 price tag for Adobe Illustrator, I am especially interested in learning open source solutions for finishing maps created in a GIS. What open source, or commonly available, software do you use to add the finishing touches (e.g. arrows, textures, colors, graphics, text, etc) to maps created in Arc, QGIS, or your choice of GIS software?
Examples of your own finished maps with comments about the open source software used and features added would be especially usefulwelcome.
