This is a free, quick and easy way to create your own hexagonal map.
I have created this tile-set and you may use it as you wish under the CC-BY licence, that means you can use it to create commercial stuff if you like.
Download it here
Now how do you use it to create your map?
I use the free software Tiled and have recorded a short tutorial to show you how.
If the values in the tutorial is to small for you to read they are: 100x60 for the map and 70x60 for importing the tile-set.
It's easy to draw your own tile-set and get your custom look. Feel free to use mine as a template if you want.
