Override for non default template

I followed this guide for an override without much success: http://stackideas.com/docs/easyblog/customizations/template-overriding

I want to override origami template, in fact, I would like to override all templates

If I put origami styles.css in override css folder, toolbar goes rogue, if I put default styles.css I miss all origami styling, even If I add it manually...

So, how to do it?
