Aon Cari Celtic, is the new free Celtic font! Feel free to download it and use it at home, for fun, on your web page or whatever! Although if you use it on your web page, a link back to my page or a credit on your site would be super nice of ya. ;-) Feel free to grab one of my Link Banners if you are linking to my page!
There is a "Read Me" PDF included in the package with some info on the font, and also some TIPS here. If you are having more troubles than are covered in there, check your font installation instructions for your computer OS.
This new free version of the Aon Cari Celtic font may be shared and used for any purpose, including publication. Enjoy!
