Yesterday I stumbled upon an article on Lifehacker that could be of some interest to all GMs out there. The service YourFonts allows you to create your own TrueType font for free. Most people use it to create a TrueType font from their handwriting but why not create a font from that runes you created for your D&D game?
The process of making a font is quite easy: you download a template as PDF or image file and either print it out and fill it with your handwriting, or you can create the font on your computer using a drawing program. Then you reupload the filled template to YourFonts. Voilá! That’s it!
For more information on this service, check out the original Lifehacker post or the official YourFonts site. Please note that there a lot of tasks in the font generation queue, so it may take some while until you can upload your templates.
