I am trying to change the font for the main blogposts (only!) in the theme Origami (link bellow). I would like to use a custom font and preferably host the font itself on my web server. I have created a folder in my child theme directory where I have placed all the .ttf files. From there on I am completely lost. I have tried using @front-face without success and I don't know if there is a more efficient method for implementing custom fonts.
I have consulted the WordPress guide at http://codex.wordpress.org/Playing_With_Fonts without any luck.
Here is the theme I am trying to edit, http://wordpress.org/extend/themes/origami
Would appreciate some help, thanks.
